# How to calculate the flight time

## Calculate flight time - this is how it works

You leave Frankfurt at eight in the morning and arrive in Tokyo at nine o'clock local time. But how do you calculate your flight time with all the time zones and international time information?

First of all you have to read the time correctly and then add the time difference. Or withdraw? Your flight time can be calculated logically with a little patience.

### Your flight time on international flights

• If the time of departure and arrival are in English, see "8 a.m." as "8 a.m." and "8 p.m." as "8 o'clock in the evening".
• Next, find out the time zones of your place of departure and your destination. You can research this on Wikipedia, for example.
• If you are flying from Germany, you have to calculate your flight time from the Central European time zone. Measured against UTC, the coordinated universal time, this zone is one hour plus, as it borders the Western European time zone in the east, which forms the central time zone for universal time.
• So if you take off at 8 a.m. it means 7 a.m. UTC, so you calculate the departure time minus an hour.
• You must calculate UTC for your destination in the same way. If you are visiting a location east of the UK, subtract one hour per time zone from your arrival time at your destination to the UK to get UTC. When heading west of the UK, add one hour per time zone.
• Make sure you know what your arrival date is when calculating UTC.
• Also, pay attention to whether it is summer time in Germany or in your destination country.
• If you were able to calculate the correct UTC for departure and arrival, you only need to compare the two times and calculate your flight time in this way.
