Jet Lag Calculator

How Jet Lag Works

Jet lag occurs when your body's internal clock is out of sync with the local time at your destination. The general rule is that it takes about one day per timezone crossed to fully adjust.

Key Factors

• Direction matters: Traveling east is typically harder than traveling west because it's easier to extend your day than shorten it.
• Number of zones: The more time zones you cross, the more severe the jet lag.
• Age: Jet lag tends to be more severe for older travelers.

Recovery Tips

• Start adjusting your sleep schedule a few days before departure
• Stay hydrated and avoid alcohol during the flight
• Get sunlight exposure at the right times to reset your body clock
• Avoid napping during daylight hours at your destination
