Jet Lag Recovery Calculator
Calculate jet lag severity and recovery timeline for travel
About this calculator
The Jet Lag Recovery Calculator helps travelers estimate how severe their jet lag will be and how long it will take to recover based on their travel details. By analyzing factors like the number of time zones crossed, travel direction (eastward or westward), departure time, and individual characteristics, this tool provides personalized recovery timelines. Understanding your expected jet lag duration allows you to better plan your schedule, adjust sleep patterns before travel, and implement effective recovery strategies to minimize disruption to your daily routine.
How to use
Enter your departure and arrival locations or time zones, travel dates, and departure time. Select your travel direction and any personal factors like age or sleep preferences that might affect recovery. The calculator will analyze your inputs and provide an estimated jet lag severity score along with a predicted recovery timeline showing when you'll likely feel back to normal.
Frequently asked questions
Why is eastward travel harder on jet lag than westward?
Eastward travel is typically harder because you're shortening your day, making it more difficult for your circadian rhythm to adjust compared to lengthening it when traveling west.
How many days does it take to recover from jet lag?
Recovery generally takes about one day per time zone crossed, but this varies based on travel direction, individual factors, and the total number of zones crossed.
What factors affect jet lag severity most?
The number of time zones crossed, travel direction (east vs west), your age, departure time, and individual sleep patterns are the primary factors influencing jet lag severity.
