Jet Lag Recovery Calculator
The jet lag recovery calculator helps you calculate how long it will take to recover from jet lag based on your travel direction and time zones crossed.. Add, subtract, convert, and schedule hours, dates, and world time zones.
Your Flight Details
Eastward travel is typically harder to adjust to.
Recovery Tips for Eastward Travel
- 1Go to bed earlier the night before
- 2Avoid caffeine 6 hours before sleep
- 3Get morning sunlight at destination
Tip: Eastward travel crosses time zones in the direction your body clock runs slower, making it harder to adjust. Expect to feel the effects for about 1–1.5 days per time zone crossed.
