Jet Lag Calculator

Estimate how long it takes to recover from jet lag. Traveling east is harder than west. Body adjusts ~1 time zone per day.

Recovery = Time Zones × 1-1.5 days (east is harder)

Eastward travel is ~50% harder. 6 zones east: 6-9 days recovery. 6 zones west: 4-6 days.

Why is flying east harder?

It's easier to stay up late (west) than wake up early (east). Your body prefers delaying its clock rather than advancing it.

How can I reduce jet lag?

Start adjusting 2-3 days before. Stay hydrated. Get sunlight at destination. Avoid alcohol. Short naps only (<30 min).
