Jet Lag Sleep Calculator

Crossing time zones can leave you exhausted, unfocused, and unable to sleep when you need to. Jet lag happens when your internal circadian rhythm gets out of sync with the local time, causing fatigue, early awakenings, daytime sleepiness, and poor concentration—especially during work trips, long flights, or tight schedules.

The Jet Lag Sleep Calculator helps you adjust faster by creating a personalized sleep plan based on your flight direction, time-zone difference, and current sleep routine. It shows you exactly when to shift your bedtime, when to wake up, whether to sleep on the plane, and how to use light exposure to reduce circadian disruption. Instead of guessing, you get a clear, science-aligned schedule that helps your body adapt smoothly and recover your energy sooner.
