OffsetJet lag time shift calculator
How far does
your body clock
need to move?
Choose your direction, the number of time zones and the shape of the trip. You will see the size of the shift and what Offset would need before it could make a timed plan.
Your time change
8-hour eastward shift
This is not the timed plan. The right hours for light, sleep, caffeine or optional melatonin also depend on your flights and usual sleep.
Why the route is not enough
Eight hours east can mean two different plans.
A daytime flight and an overnight flight do not give you the same chance to sleep. A direct trip and a two-stop trip do not put you on the ground at the same times.
Offset uses the itinerary and your usual sleep instead of giving every eastward or westward traveler the same checklist.
What the full app will ask for
