Tips to Minimize Jet Lag

What is it?

Jet lag happens when your body’s internal clock is not adapted with the new environment and time zone.

It can mess with your sleep, make you fatigue, have lack of energy, and even gastrointestinal issues.

So this jet lag recovery calculator works just like professional tools like the Jet Lag Rooster, and jet lag calculator Sleepopolis: it works out the time difference and direction of travel and provides personalized recommendations to reduce jet lag.

Jet lag feels worse when you travel east because you lose time, but it’s easier when you go west since you gain time

Research confirms that light exposure, meal timing, and melatonin at the right times can reset your body clock and reduce jet lag.

Enter your travel information

Start by selecting your departure city, arrival city, and their respective time zones. Your calculator utilizes these to determine how many time zones you’re traveling across.

Enter travel dates and times

Input your arrival time and departure time. This helps your calculator to be aware of whether you’re traveling west or east because that dictates how your internal body clock adjusts.

Enter your stay length

If you’ll be staying at your destination for a few days or weeks, the calculator does factor that into account when computing your total recovery time.

Automatic time zone detection (Optional)

You can alternatively click “Detect My Time Zone” to have it automatically detect your current location from your browser settings, without needing to enter it manually.

Calculate your Jet Lag Recovery Time

The moment you click “Calculate Jet Lag”, the calculator instantly processes your entries and shows:

  •  Number of time zones covered
  • Travel in an east or west direction
  • Jet lag severity (mild, moderate, or severe)
  • Recovery time in days
  • Helpful tips to minimize jet lag

Most of the travelers that followed these tips experience reduced fatigue and faster adjustment to new time zones.

Does it really work?

Yes, shifting your body clock before and during your trip can help reduce jet lag symptoms.

The Center for Disease Control (CDC) recommends adjusting your schedule and light exposure when traveling internationally (CDC, Yellow Book, 2016).

Why use this Jet Lag Calculator?

  • Customized to your individual travel schedule and time zone difference.
  • Provides a specific, step-by-step plan.
  • Based on circadian rhythm science and CDC recommendations.

How to calculate jet lag recovery time Manually?

Most of the time It takes about one day to get used to a time zone when you fly east, and about half a day per time zone when you fly west.

So, if you travel from Los Angeles to London, you cross 8 time zones east, that means it might take around 8 days for your body to feel normal again.

And if you fly from Paris to New York which is 6 time zones west, you will need aoudad 3 days to get fully recovered from the jet lag.
