Planning across the country
When you fix a call or a broadcast for people in several parts of Mongolia, give the time with its zone, or use the converter to show every zone at once.
Where most people are
Measured by the people living in towns of 15,000 or more (GeoNames figures), the busiest clock in Mongolia is the one kept in Ulan Bator, UTC+8 in January: about 1.4 million people, or 92% of the total across all the zone areas. Next comes the clock of Ulaangom (UTC+7) with about 122,000.
A worked example
When it is 9:00 am in Ulan Bator in January, it is 8:00 am in Ulaangom.
The widest gap inside the country
The two clocks that are farthest apart differ by 1 hour in January, and by the same amount in July. On the map, the main cities run from Ulaangom at about 92.1° east to Ulan Bator at about 106.9° east. By the sun alone those two are about 59 minutes apart.
The sun across Mongolia
Clocks are set by law, but the sun keeps its own time. In Ulaangom, the most westerly of the main cities (about 92.1° east), the sun is highest at about 12:52 pm by the clock in January. In Ulan Bator, the most easterly (about 106.9° east), it is highest at about 12:52 pm. The closer that figure is to 12:00, the better the clock fits the daylight in that city.
Mongolia and the rest of the world
When it is 12:00 noon in Ulan Bator, it is 9:30 am in India; 4:00 am in London in January and 5:00 am in July; 11:00 pm the previous day in New York in January and 12:00 am in July. Other parts of Mongolia are earlier or later than that by the amounts in the table at the top of this page.
