Travel Jet Lag Recovery Calculator
Calculate jet lag duration and recovery time based on time zone differences and travel direction
About this calculator
The Travel Jet Lag Recovery Calculator helps travelers estimate how long jet lag symptoms will last and plan their recovery time after crossing multiple time zones. This tool considers the number of time zones crossed and travel direction (eastward or westward) to provide accurate recovery estimates. Understanding your jet lag duration helps you schedule important meetings, adjust sleep routines, and minimize the impact of circadian rhythm disruption on your trip or return home.
How to use
Enter your departure and arrival time zones or select your origin and destination cities. The calculator will automatically determine the number of time zones crossed and travel direction. Based on this information, you'll receive an estimated jet lag duration and recovery timeline with tips for faster adjustment.
Frequently asked questions
Why is eastward travel harder than westward?
Traveling east requires advancing your body clock, which is more difficult than delaying it when traveling west. Most people naturally have slightly longer circadian rhythms.
How long does jet lag typically last?
Jet lag generally lasts 1-2 days per time zone crossed. Eastward travel may take longer to recover from than westward travel.
What factors affect jet lag severity?
Age, number of time zones crossed, travel direction, flight timing, sleep quality, and individual circadian rhythm sensitivity all influence jet lag duration and intensity.
