Your jet lag plan connects with the rest of the Voyasee toolkit, so the same route gets safer, cheaper and easier to prepare.
The planner anchors everything to your CBTmin — the low point of your body clock, roughly two hours before your usual wake time. Light after CBTmin shifts you earlier (for eastward trips); light before it shifts you later (for westward trips). Because mistimed light can push your clock the wrong way, the tool gives exact seek-light and avoid-light windows instead of generic advice. For very large shifts it checks whether adapting the opposite direction is faster and flags it as Direction optimised. When live data is available for your arrival date it layers in destination temperature, precipitation and air quality from OpenWeather; wherever a specific data point isn't available for that date, the tool falls back to a clearly-labelled built-in seasonal estimate rather than guessing.

Crossing several time zones can leave your watch on destination time while your body still follows home. The Voyasee Jet Lag Recovery Planner turns your route, arrival schedule, sleep habits and live destination conditions into a practical recovery timeline for the days before your flight, the time onboard and the first days after landing.
Enter your airports or cities, travel dates, arrival time, cabin, normal sleep schedule and first important event.
Jet lag is often described as simple tiredness, but the travel experience can be wider than that. A large time-zone change may disturb sleep, concentration, appetite, digestion, mood and physical performance. It can affect a business presentation, a wedding, a family holiday, a cruise departure, a sporting event or the first full day in a destination. The problem is not only how long the flight lasts. The deeper problem is that your internal clock may still be expecting night when the destination has started its morning, or expecting daytime when you need to sleep.
The Voyasee Jet Lag Recovery Planner helps organise that mismatch before it becomes an arrival-day guessing game. It calculates the time shift, estimates the body-clock direction, builds timed light windows, suggests caffeine and nap limits, creates an onboard strategy and prepares a personal recovery timeline. When current information is available for the selected place and date, the planner also applies live destination weather and air-quality data powered by OpenWeather through the Voyasee Weather Bridge.
The result is designed for practical travel. You do not receive only a paragraph telling you to sleep well and drink water. You receive a route command, Jet Lag Load Score, adaptation estimate, live light score, body-clock recovery curve, seek-light and avoid-light map, destination environment signals and day-by-day actions. You can then copy the plan, save it to a calendar, add an event to Google Calendar, share the route or print the timeline.
What the Jet Lag Recovery Planner Does
The planner combines travel timing with a body-clock model. It reads your origin and destination, understands the local time zones, calculates the effective clock change and decides whether your schedule should move earlier or later. It then uses your normal wake time to estimate your body-clock low point, often called CBTmin. In this planner, CBTmin is estimated at roughly two hours before your usual wake time.
That low point matters because light can shift the internal clock differently depending on when it reaches you. The planner uses this timing relationship to create two separate windows: a period when bright light may support the intended shift and a period when strong light may push the clock in the wrong direction. This is why the result is more specific than general advice to “get sunlight after landing.” The time of that light matters.
For a moderate eastward journey, the body normally needs to move earlier. For a westward journey, it normally needs to move later. For a very large shift, however, the planner compares both possible adjustment directions. If moving the apparent “long way” around the 24-hour clock is estimated to take fewer days, the tool chooses that direction and displays a direction-optimised notice.
The planner also recognises that jet lag is not created by clock difference alone. It considers estimated flight length, cabin type, arrival time, sensitivity, chronotype, trip purpose, traveller mode, live light quality and environmental strain. These inputs contribute to the Jet Lag Load Score and shape the wording of the personal timeline.

Who Can Benefit From This Tool?
The planner is useful for anyone crossing time zones, but it becomes especially valuable when the first days of a trip matter. A leisure traveller may want to avoid losing two holiday days to poor sleep. A business traveller may need to perform well in a morning meeting after an evening arrival. A couple may have a wedding or special dinner soon after landing. A family may need a calmer first night for children. A sports traveller may need alertness, coordination and a stable routine before an event.
It also helps travellers compare flight schedules before booking. Two fares may reach the same city, but one may land at a kinder local time. A route that arrives in the late evening may allow a direct move toward local bedtime, while another that arrives at dawn may demand a full destination day after limited cabin sleep. The planner makes those differences easier to see.
Frequent travellers can use the tool to avoid relying on the same habit for every route. The advice for London to Bali is not identical to Bali to London. New York to Tokyo is not the same as Tokyo to New York. Sydney to London brings a different clock problem from São Paulo to Madrid. The direction, effective shift, date, daylight and arrival time all matter.
Search by Airport Code, City or Country
The route fields accept airport codes, city names and country searches. A built-in database of about 1,000 airport records gives the planner fast access to major international airports, regional hubs and popular travel destinations. Entering a familiar code such as JFK, LHR, HND, DXB, DEL, SIN or SYD can produce a quick match without requiring an outside lookup.
The search system ranks exact airport-code matches first, followed by city, airport name and country matches. This helps users who know only part of a name. Typing “Tokyo” can surface Tokyo airports, while entering “Japan” can help reveal options within the country. The suggestions display useful location context so that travellers can choose the correct airport rather than selecting a city with a similar name.
If a city is not present in the built-in airport list, the planner can use live geocoding through the Voyasee Weather Bridge. The bridge is connected to OpenWeather location data and returns coordinates for the requested place. The tool then uses those coordinates to request current destination information and determine the local time offset. This means the search can extend beyond the built-in airport records while keeping the user-facing form simple.
The bridge keeps provider credentials on the Voyasee server rather than placing them in the public page. The browser communicates with Voyasee’s own same-origin endpoints, and the server handles the provider connection. For the traveller, the experience is simply a place search followed by a live result.
Departure Date, Departure Time, Arrival Date and Arrival Time
The date and time fields are essential because the planner does not treat every arrival as the same. It converts the entered local departure and arrival times through the origin and destination time zones. Using recognised time-zone names allows the calculation to reflect daylight-saving time where it applies.
The tool estimates total travel time from those local timestamps. If the entered schedule produces an impossible or unreliable duration, it uses a great-circle distance estimate between the two locations. That estimate considers the distance between coordinates, an average cruising speed and additional ground time for taxiing and airport movement. It is a planning estimate, not a replacement for the airline schedule, but it gives the scoring engine a realistic fallback.
Arrival timing influences the first-day strategy. A traveller landing in the morning may need to remain awake through the destination day, use carefully timed light and limit any nap. A traveller arriving in the evening may be better served by a light meal, low stimulation and a direct move toward local bedtime. A late-night arrival may create less daylight opportunity but a clearer sleep target.
Trip Length and Short-Trip Mode
The trip-length menu separates journeys under 48 hours, three to four days, five to nine days and ten days or longer. This is important because complete adaptation is not always the best goal. For a brief trip, forcing a large clock change may leave the traveller adjusting in both directions within a few days.
When short-trip mode is selected, the planner reduces the pre-flight adjustment period and advises the traveller not to force full adaptation. It focuses on protecting key hours, using one short strategic nap where needed and timing light around the moments that matter most. This can be useful for a short business visit, flight crew positioning, a conference or a brief event trip.
For a longer stay, the planner can place greater emphasis on shifting toward destination time. The personal timeline extends through arrival day and the next recovery days so the traveller can repeat consistent light, meal, caffeine and sleep anchors.
Travel Purpose and Readiness Time
The travel-purpose menu includes vacation, business meeting, wedding or event, sports or performance and family trip. Purpose changes the pressure placed on the arrival plan. A flexible holiday can absorb a slower morning. A presentation, wedding ceremony or race cannot always be moved.
The readiness-time field lets you identify the local time of the first important moment. It might be a 9:00 AM meeting, an afternoon cruise departure, an evening wedding, a morning tour or a sporting event. When the selected purpose involves business, weddings or performance, the planner activates readiness guidance and adds a preparation block to the timeline.
This block can protect time for light, hydration, a light meal and preparation while warning against a long pre-event nap. The planner also adds an event-pressure component to the Jet Lag Load Score, because the same clock shift feels more demanding when the traveller has little recovery room.
Traveller Mode: Adults, Families, Babies and Sensitive Travellers
Adult mode is suitable for most solo travellers, couples and general leisure or business travel. It treats timed light, caffeine, naps and sleep as the main recovery levers.
Family mode adapts the advice for travel with children. It encourages outdoor play as a practical form of light exposure, keeps naps short enough to protect bedtime and recognises that snacks, comfort and a calm first evening can be more useful than an aggressive clock shift.
Baby mode keeps the expectations even gentler. Feeding, changing, cabin sleep and irregular naps can shape the first days more than a rigid schedule. The planner includes a clear reminder not to give children sleep aids unless a paediatric clinician has advised it.
Senior or extra-sensitive mode raises the caution level in the score and timeline. It encourages gradual adjustment, hydration and professional guidance around medicine or sleep aids. This mode can also suit travellers who already know that long flights affect them strongly, even if they are not older.
Cabin Type and Sleep Realism
The cabin selector includes economy, premium economy and business or first class. This does not assume that a higher cabin removes jet lag. Instead, it adjusts how realistic onboard sleep may be and how much arrival fatigue the traveller may carry.
Economy mode assumes lighter, more interrupted sleep. The timeline recommends an eye mask, earplugs, hydration and movement while placing tighter limits on arrival-day naps. Premium economy assumes better recline and a more realistic partial sleep block. Business or first class makes a destination-night sleep block more achievable, but the planner still warns against sleeping deep into destination daytime.
This function can support booking decisions. A business-class fare may not be practical, but a better arrival time, an airport hotel or an additional recovery day may achieve part of the same goal. The Voyasee Trip Budget Calculator can help compare those choices.
Normal Wake Time, Bedtime and Chronotype
Your normal wake time and bedtime give the planner a home routine to work from. The wake time is especially important because the body-clock low point is estimated at roughly two hours before it. From there, the tool translates that point into destination local time and builds light windows around it.
Chronotype lets you identify as an early bird, normal sleeper or night owl. People differ in when they naturally feel alert and sleepy. A night owl may find an eastward phase advance especially difficult, while an early bird may struggle to stay awake late enough during a westward shift. The planner uses the selected chronotype as part of the personalised interpretation.
These settings do not need to be perfect. Use the times that describe a normal week rather than an unusual travel day. The more closely they reflect your ordinary rhythm, the more meaningful the body-clock chart and timing windows become.
Sensitivity, Units, Caffeine and Sleep-Aid Preferences
Sensitivity can be set to low, normal or high. A higher setting adds weight to the Jet Lag Load Score and creates a more cautious result. A low-sensitivity traveller may still feel tired after a difficult route, but the score recognises that personal experience can differ.
The units selector displays destination temperatures in Celsius or Fahrenheit. Temperature is included in the arrival environment card and meal-timing guidance when live information is available.
Caffeine use can be set to none, light, normal or heavy. The planner calculates a cutoff before target bedtime. High sensitivity creates a longer gap, and heavy caffeine use adds another buffer. No-caffeine mode replaces the caffeine suggestion with daylight and movement.
The sleep-aid selector lets users hide the notes, display a caution window or indicate that they will ask a clinician. The tool does not prescribe melatonin, antihistamines, CBD or prescription sleep medicine. It keeps these items inside a caution framework and links to the Voyasee Medicine & Restricted Items Checker for packing and destination-rule preparation.
The Plain-Language Scenario Coach
The scenario box offers a faster way to prepare the form. A traveller can write a sentence such as: “I fly from New York to Tokyo, land at 6 AM and have a meeting at 9 AM the next day. I sleep badly in economy.” The parser reads the order of the places and looks for useful details such as arrival timing, purpose, traveller type and cabin.
The coach then fills the matching fields where it can, allowing the traveller to review and correct them before building the plan. It is especially useful when the itinerary feels easier to describe in a sentence than to enter field by field.
The final plan still comes from the same route, time-zone and body-clock calculations. The scenario box is simply a convenient input method. Travellers should check the dates, times and airport matches before using the result.
How the Body-Clock Engine Works
The planner compares two possible forms of adaptation: advancing the clock earlier and delaying it later. In its model, an advance is estimated at about one hour per day, while a delay is estimated at about one and a half hours per day. For a normal eastward journey, advancing is often selected. For a normal westward journey, delaying is often selected.
For a very large shift, the apparent direction may not be the shortest route around a 24-hour clock. The engine therefore calculates both options. When the opposite direction is estimated to require fewer days, the dashboard displays a direction-optimised notice and uses that direction throughout the timeline.
The body-clock low point is translated into destination time for arrival day and the following days. The selected adjustment rate moves that point earlier or later each day. Seek-light and avoid-light windows are then created around it. For an advance, the tool seeks light after the low point and avoids light before it. For a delay, it seeks light before the low point and avoids light after it.
When the effective shift reaches eight hours or more, the tool displays a circadian precision warning. This reminds the traveller that mistimed bright light near the low point can work against the plan. The result is not intended as medical treatment, but it gives the user a clearer timing structure than generic arrival advice.
Jet Lag Load Score: Mild, Moderate, High or Extreme
The Jet Lag Load Score runs from 0 to 100. Scores are grouped into Mild, Moderate, High and Extreme levels. The score is a travel-planning estimate rather than a diagnosis.
The calculation considers the effective hours of body-clock movement, whether an advance or delay is needed, estimated flight duration, cabin type, sensitivity, traveller mode, event pressure and arrival time. It also uses the live light score and arrival environment load. A route with a large advance, economy cabin, high sensitivity, early-morning arrival and poor destination conditions may score much higher than a small shift with a flexible schedule.
The score is valuable because it explains why two trips with a similar flight length can feel different. A ten-hour flight with a modest time change may be easier than a shorter flight crossing a difficult set of zones. A comfortable arrival time may reduce pressure, while a major event shortly after landing can increase it.
Use the score as a planning signal. A high result may justify a quieter first day, an earlier arrival, a simpler transfer or an extra hotel night. It may also be a reason to move a tour, long drive or important meeting away from arrival day.
Live Light Score
The live light score estimates how useful destination light may be for the selected date. It considers daylight length, available sunshine, UV, cloud cover, precipitation and PM2.5 where those data points are available. The result is displayed beside the time shift, Jet Lag Load Score and adaptation estimate.
A strong score suggests that outdoor light during the recommended window may be easier to use. A weaker score may reflect cloud, rain, limited daylight or poor air quality. In that case, the command recommends the brightest safe outdoor window or bright indoor light.
The tool also handles high-latitude conditions. During polar night, natural light may be too limited to act as the main timing cue. During polar day, constant daylight can make it difficult to create a clear night. The timeline then advises artificial brightness during the intended day and blackout curtains or an eye mask at bedtime.
OpenWeather Live Data Through Voyasee Weather Bridge
The planner receives live weather and air-quality information through the Voyasee Weather Bridge. The bridge communicates with OpenWeather while keeping provider credentials on the server. This prevents the public tool page from exposing a private weather key.
For a supported destination and date, the bridge can return current conditions, daily forecast information and air-quality components. The planner uses destination temperature, precipitation probability, cloud cover, sunrise or sunset information where supplied, PM2.5, PM10 and an estimated air-quality score.
OpenWeather provides global weather products, location search and air-pollution information. Travellers who want to understand the data source can read the official OpenWeather API overview, OpenWeather Geocoding API documentation and OpenWeather Air Pollution API documentation.
The live request is made only when a traveller builds a plan. Results are temporarily cached to reduce repeated provider requests. If a request is blocked, times out or does not include a specific value for the selected date, the planner continues with its internal seasonal calculation and labels the result as estimated.
Fallback Daylight and Seasonal Estimates
A travel tool should not become unusable because a provider has no value for a distant date or a temporary request fails. The planner therefore includes a latitude-and-season daylight estimate. It uses the destination’s position and arrival month to estimate sunrise, sunset and day length.
The fallback also supplies conservative default values for cloud, precipitation and UV so that the scoring and timeline can continue. The dashboard clearly distinguishes live destination light from estimated information. This means the recovery logic still works even when the live layer is incomplete.
The estimate is a planning aid, not a weather forecast. Travellers should check the current destination forecast again near departure, particularly when outdoor conditions affect health, transport or planned activities.
Arrival Environment Load
The Arrival Environment Load is grouped into Low, Moderate, High or Heavy. It looks beyond the clock shift and asks whether the local conditions may add strain to the first day.
Heavy cloud, a high chance of precipitation, elevated PM2.5 or PM10, very hot or very cold temperatures and polar conditions can increase the environment load. A traveller may feel worse not because the time-zone calculation is wrong, but because flight fatigue is meeting heat, poor air, rain, limited daylight or extreme cold.
The result appears as an insight card with available PM2.5, precipitation risk and temperature. If the airport or place is above 2,000 metres, the planner can also show an altitude note because altitude may add to fatigue and hydration needs.
Use this card to shape arrival day. A high environment load may support a shorter outdoor session, a shaded walk, a bright indoor alternative or a less demanding schedule. The Voyasee Smart Travel Hub can provide additional destination context.
Public Holiday Arrival Alerts
The planner checks the selected arrival date through Voyasee Country Intelligence. If the date is recognised as a public holiday in the destination country, an alert can appear in the dashboard.
This matters for jet lag preparation because pharmacies, shops and services may close or operate reduced hours. A traveller planning to buy an eye mask, medicine, snacks, toiletries or other recovery essentials after landing could find fewer options.
The alert includes the holiday name where available and recommends arranging essential items before flying. Public holiday information is provided by Voyasee’s own country-data layer rather than relying on a third-party country page inside the tool.
The Recovery Dashboard
The dashboard begins with four summary metrics: time shift, Jet Lag Load Score, adaptation estimate and live light score. Beneath those metrics is the route command, which states whether the clock should move earlier, later or remain close to normal.
The command includes the main seek-light and avoid-light windows. If direction optimisation is active, the dashboard explains that the plan is using the shorter adaptation direction. Large shifts receive a precision notice. Short trips receive a reminder not to force full adaptation. Business, wedding and sports trips receive readiness wording.
The insight cards explain the body-clock time at arrival, the role of the low point, current destination light, score drivers, environment load, caffeine window, traveller mode and cabin realism. Holiday and altitude alerts can be added when relevant.
Body-Clock Recovery Curve
The recovery curve visualises the estimated mismatch over the first days. It does not promise that every person will recover on the same schedule. Instead, it gives a simple picture of the model’s expected movement toward the destination clock.
The curve helps set expectations. A traveller may sleep better after the first night but still experience early waking or afternoon tiredness on day two. The chart shows that recovery is usually a process rather than a single event.
Use the chart when arranging important activities. If the greatest mismatch is concentrated on arrival day and day two, save demanding tours, driving or presentations for later where possible.
The 24-Hour Light and Caffeine Map
The day map divides destination time into 24 hourly sections. Colour blocks identify the recommended light window, avoid-light window and caffeine period. A marker shows the estimated CBTmin.
This visual makes the timing easier to understand than a paragraph alone. Travellers can quickly see whether the strongest action belongs in the morning, afternoon, evening or overnight hours.
The map also explains why random exposure may not be helpful. Bright light close to the wrong side of the low point can move the clock away from the intended direction. The tool’s value comes from placing the actions in the right order.
Pre-Flight Timeline
The planner creates between one and four pre-flight days depending on effective shift and trip length. For an advance, it moves wake time and bedtime earlier while encouraging bright light after waking and dimmer evenings. For a delay, it recommends late-afternoon or evening light, darker early mornings and later sleep.
The amount of movement grows gradually across the pre-flight days. The tool also adds a practice caffeine cutoff so the traveller begins protecting the target bedtime before departure.
These are gentle timing changes, not a demand to rebuild an entire routine. Even a partial shift can reduce the contrast between home time and destination time.
In-Flight Strategy
After boarding, the timeline recommends switching the watch and meal thinking toward destination time. It schedules a main onboard sleep block according to the chosen adjustment direction and cabin type.
Economy and premium travellers receive practical suggestions such as an eye mask, earplugs and a protected partial sleep block. Lie-flat passengers are encouraged to use the seat strategically rather than sleeping into destination daytime.
Before arrival, the plan adds hydration and movement while discouraging alcohol as a recovery shortcut. The goal is to arrive ready to follow the destination-day light and sleep schedule.
Arrival-Day Plan
Arrival day contains the most detailed actions. It begins with the seek-light and avoid-light windows. The planner describes light as the highest-leverage action because timing can affect the direction of the shift.
The timeline includes a last-caffeine time, a destination-time meal, a nap rule and target bedtime. If arrival is early enough, the tool permits one short nap of about 20 minutes before mid-afternoon when exhaustion makes it necessary. A late arrival normally receives a no-nap recommendation so that local bedtime remains possible.
The meal event encourages eating according to destination time and avoiding a very large late dinner. Temperature information is included when live data are available. Readiness mode adds a preparation block before the first important event.
Day Two and Day Three
Recovery does not stop after the first sleep. Day two and day three repeat the light anchor, avoid-light period, normal local meals, caffeine cutoff and target bedtime.
Repeating the same cues helps make the destination schedule more consistent. If the live day is cloudy, the timeline recommends the brightest safe outdoor period or a suitable bright-light source. If the local environment is uncomfortable, travellers can adapt the duration while keeping the timing.
The repeated schedule is especially useful for long stays. It reduces the temptation to respond to each tired moment with a long nap or late coffee.
Caffeine Timing
Caffeine is treated as a timed alertness aid, not a substitute for sleep. Normal users are generally advised to stop about six hours before target bedtime. High-sensitivity mode expands that buffer to about eight hours. Heavy use adds additional caution.
The arrival card normally recommends caffeine in the destination morning rather than late in the local day. No-caffeine users receive daylight and movement guidance instead.
Following the cutoff protects the first local night. A late coffee may solve an afternoon slump but create a much larger problem at bedtime.
Medicine and Sleep-Aid Caution
The dashboard places a health caution close to the results. Melatonin, sedating antihistamines, CBD and prescription sleep medicines can have side effects, interactions and destination restrictions. The planner does not tell a user to take them.
The NCCIH melatonin information page explains the role of melatonin and important safety considerations. Travellers using regular medicine, sedatives, stimulants or sleep products should speak with a qualified clinician where appropriate.
Before packing medicine, use the Voyasee Medicine & Restricted Items Checker and confirm rules through official destination and transit sources.
Copy Plan, Share Link, Calendar, Google Calendar and Print
Copy Plan places the route command and timeline into a format that can be saved in notes or shared with a travel companion. Copy Share Link creates a URL containing the main route dates and times, allowing the same form to be opened again.
Download Calendar creates an ICS file containing the recovery events. It can be imported into many calendar apps. Add to Google Calendar opens a prepared event for the first arrival action. Print creates a cleaner result suitable for paper or PDF printing.
These functions reduce the need to remember every instruction while tired. Save the plan before departure and keep the most important actions visible on arrival day.

Common Jet Lag Mistakes the Planner Helps Prevent
Taking a long late nap
A long afternoon sleep can make the first local bedtime much harder. The timeline limits arrival-day naps and moves late arrivals directly toward bedtime.
Using caffeine too late
Caffeine can improve alertness but delay sleep. The tool places a cutoff several hours before the target bedtime and uses a longer buffer for sensitive travellers.
Seeking bright light at the wrong time
Light can shift the body clock in either direction. The day map separates seek-light and avoid-light windows so the traveller can follow the intended shift.
Planning too much on arrival day
A high Jet Lag Load Score or environment load is a sign to reduce driving, complex transfers and demanding activities where possible.
Ignoring the first important event
Readiness time helps the planner prepare for the event rather than building a generic holiday schedule.
Packing medicine without checking the route
Sleep products and prescriptions may have restrictions. The medicine link keeps that issue visible before departure.
External Travel-Health Reading
The CDC Yellow Book page on Jet Lag Disorder explains the mismatch between the internal biological clock and local time and describes common symptoms. The public CDC Travelers’ Health jet lag page provides practical information for travellers.
These sources support the article’s emphasis on sleep timing, light, meals, caffeine, exercise and careful planning. The Voyasee tool translates those broad travel-health principles into a route-specific schedule, but it remains an educational planner rather than medical treatment.
Jet Lag Recovery Planner FAQ
Is the Jet Lag Recovery Planner free?
Yes. The planner is free to use and does not require a signup. Some optional partner links may earn Voyasee a commission.
Does it work with airport codes and city names?
Yes. The tool searches a large built-in airport database and can use live geocoding for places outside that list.
What is CBTmin?
CBTmin refers to the low point of the body clock. The planner estimates it at roughly two hours before your normal wake time and uses it to organise light windows.
Why can the planner choose the opposite direction?
For a very large time-zone shift, moving the other way around the 24-hour clock can sometimes require fewer estimated adaptation days. The direction optimiser compares both options.
What does the Jet Lag Load Score mean?
It is a 0-100 planning estimate based on time shift, direction, flight length, cabin, sensitivity, arrival timing, purpose, light and environment. It is not a medical diagnosis.
Where does the live weather information come from?
Weather, location and air-quality information are supplied by OpenWeather through the Voyasee Weather Bridge. The bridge keeps provider credentials on the server.
What happens when live data are unavailable?
The planner uses a clearly labelled seasonal daylight estimate so that the recovery schedule can still be created.
Does it check public holidays?
Yes. Voyasee Country Intelligence can add a holiday alert for the selected arrival date when a matching public holiday is found.
Can I use it for a trip under 48 hours?
Yes. Short-trip mode reduces the pre-flight shift and focuses on protecting important hours instead of forcing complete adaptation.
Can families use the planner?
Yes. Family and baby modes add gentler pacing, shorter nap guidance and child-specific cautions.
Does the planner recommend melatonin?
No. It only offers a caution setting and advises travellers to speak with a clinician and check destination rules where appropriate.
Can I save the result?
Yes. You can copy the plan, copy a share link, download an ICS calendar, add an event to Google Calendar or print the result.
Final Thoughts
A long-haul journey is easier to manage when the first day is planned before departure. The Voyasee Jet Lag Recovery Planner combines route timing, time zones, body-clock direction, sleep habits, light exposure, caffeine, naps, live destination conditions and arrival priorities inside one readable result.
The most valuable part is not a single score. It is the order of actions: adjust gently before departure, switch thinking toward destination time onboard, use the correct light window after landing, limit caffeine and naps, eat on local time and protect bedtime. Those actions give the internal clock clearer signals while reducing common arrival mistakes.
Use the planner before booking when arrival timing matters, and rebuild the result after the itinerary is final. Save the timeline, connect it with the rest of the Voyasee tools and give the first days of the trip enough space to work.
