Time in Mongolia

Time in Mongolia
  Western Mongolia Time (UTC+7)
  Eastern Mongolia Time (UTC+8)

Time in Mongolia is officially represented by the Mongolian Standard Time (UTC+08:00). However, the far western provinces of Khovd, Uvs and Bayan-Ölgii use UTC+07:00.

Daylight saving time

Mongolia used daylight saving time in 1983–1998, 2001–2006 and 2015–2016. However, Mongolia observes time almost exactly an hour ahead of its geographical time zone, with its border between UTC+7 and UTC+8 being almost exactly the longitudinal line of 97.5° E (which is really the designated border for between UTC+7 and UTC+6), so all of Mongolia could be said to be on permanent daylight/summer time.

Notes
