Timezones in Mongolia

There are altogether 3 official timezones in Mongolia, but practically only 2 different times. Countries with a large distance from West to East are often devided into two or more timezones to adjust daytimes to the position of the sun. Timezones are always computed relatively to UTC, the "Universal Time Coordinated".

In Mongolia exists a time difference of 1 hour between the East and the West. Mongolia has no time difference between summer and winter. A daylight saving time doesn't exist.

No more daylight saving time in Mongolia

Due to the sun's orbit around the equator, the days are longer in summer (June to September in the northern hemisphere). Countries that switch to daylight saving time in the summer months align the daylight phase with the human rhythm. Unused bright morning hours are thus shifted into the evening (more information on daylight saving time here).

Due to its distance from the equator, the impact would be significant in Mongolia. Ulaanbaatar is located 5,300 km from the equator. A day in midsummer would then not last from 04:51 to 20:57, but from 05:51 to 21:57. Nevertheless, in 2016 it was decided to finally abandon daylight saving time in Mongolia.
