About this tool

The old rule of thumb holds surprisingly well: about 1 recovery day per time zone crossed — and flying east is harder than west (~1.5×), because advancing your clock fights biology more than delaying it. The proven helpers: shift sleep 1 hour/day toward the destination before departure, get morning light after eastward flights (evening light after westward), stay awake to local bedtime on day one, hydrate, and go easy on alcohol in-flight. This advisor estimates your recovery window and gives the schedule.
