Jet Lag Recovery Calculator
Calculate jet lag severity and recovery time based on travel direction and time zone difference
About this calculator
The Jet Lag Recovery Calculator helps travelers estimate how long it will take to overcome jet lag based on their trip details. By analyzing your travel direction (eastward or westward) and the number of time zones crossed, this tool provides personalized recovery timelines. Eastward travel typically causes more severe jet lag than westward travel due to our natural circadian rhythms. Understanding your expected recovery time helps you plan important meetings, adjust sleep schedules, and manage expectations for your post-travel productivity.
How to use
Enter your departure and destination time zones or select the number of time zones you'll cross. Choose your travel direction (east or west). The calculator will instantly display your jet lag severity level and estimated recovery time in days, helping you plan your schedule accordingly.
Frequently asked questions
Why is eastward travel worse for jet lag?
Eastward travel works against your natural circadian rhythm, making it harder to fall asleep earlier. Your body clock naturally runs slightly longer than 24 hours.
How long does jet lag typically last?
Recovery time varies by individual and distance traveled. Generally, expect one day of recovery per time zone crossed when traveling east, and slightly less when traveling west.
Can I prevent jet lag completely?
While you can't eliminate jet lag entirely, you can minimize it by adjusting sleep schedules before travel, staying hydrated, and managing light exposure upon arrival.
