Altai, Mongolia · UTC+7 ☆

Altai is in the Asia/Hovd timezone (HOVT/UTC+7, DST to UTC+8 in summer). The capital of Mongolia’s Govi-Altai province has a population of around 20,000.

Altai is the administrative center of Mongolia’s Govi-Altai province, sitting in western Mongolia near the Altai mountain range. It is not a large city, perhaps 20,000 people, in a region of semi-desert steppe and mountain. Mongolia is vast, and cities like Altai are the sparse urban nodes of an enormous, sparsely populated landscape.

The clock is UTC+7, using the IANA identifier Asia/Hovd (named for Khovd, the main city of western Mongolia). Mongolia is one of the few countries that officially uses two timezones. Ulaanbaatar and most of the country run on UTC+8. The western provinces, including the Altai region, run on UTC+7.

This creates a one-hour internal time difference within Mongolia. The capital is one hour ahead of Altai. For administrative and government purposes, this requires coordination.

Seasonal shifts and summer alignment

Mongolia observes daylight saving time, moving clocks forward in late March and back in late September. So UTC+7 becomes UTC+8 in summer, which means western Mongolia matches the capital’s standard time in summer months.

The Altai mountain range that gives this city its name is one of the world’s significant mountain systems, running through Russia, Kazakhstan, Mongolia, and China. The city serves as the gateway to this region and to extensive gold and copper mining operations in the surrounding area.

9am in Altai is 2am in London during European winter.
