History
How Mongolia keeps time.
Mongolia has had a relatively straightforward timezone history. The country primarily used Ulaanbaatar Time (UTC+08:00) as its standard time, reflecting its alignment with Beijing Standard Time.
Mongolia first observed daylight saving time in 1983, implementing clocks forward one hour during summer months. The country continued this practice through the 1990s but has since discontinued daylight saving observance.
In 2007, Mongolia officially adopted two time zones to better reflect its vast east-west expanse. The western region, including Hovd province, was placed on UTC+07:00, while the rest of the country remained on UTC+08:00. This change acknowledged the significant geographic spread of Mongolia's territory.
Did you know?
Things about Mongolia's time.
Mongolia's two time zones reflect its enormous geographic spread—over 2,400 kilometers from east to west. The UTC+07:00 zone covers the western region around Hovd, while the more populous eastern region including Ulaanbaatar uses UTC+08:00, aligning with Beijing Standard Time.
The decision to implement daylight saving time in 1983 was part of broader Soviet-influenced timekeeping practices during the socialist era. The subsequent discontinuation in the 1990s reflected Mongolia's move away from such policies following democratic reforms.
Travelers crossing from the western region to Ulaanbaatar should adjust their clocks forward by one hour as they travel east. This change is particularly noticeable given Mongolia's vast distances and the time difference between western and eastern towns.
