The warm light starts well before that: evening golden hour opens at 17:49, giving 41 minutes of low golden light before the sun reaches the horizon. Sunset is not the end of the light either.

Is the day getting longer or shorter in Ulan Bator right now?
Ulan Bator gets 11h 38m of daylight today, from sunrise to sunset. Tomorrow will be 3 minutes 26 seconds shorter. Over the next seven days Ulan Bator loses 23 minutes 59 seconds of daylight.
That pace is not constant. In Ulan Bator the day length changes fastest around March, near the equinox, when it moves by about 3 minutes 30 seconds per day, and it slows almost to a stop at the solstices in June and December. The word solstice means exactly that: the sun standing still.
When are the earliest and latest sunrise and sunset in Ulan Bator?
The earliest sunset of 2026 in Ulan Bator falls on 11 December at 16:59, 10 days before the December solstice, and the latest on 25 June at 20:55.
Sunrise runs on its own schedule: earliest on 16 June at 04:52, latest on 1 January at 08:41, 11 days after the December solstice. The four dates in the table below do not line up with the solstices, and they are not supposed to. Earth's orbit is slightly elliptical and its axis is tilted, so the sun runs a few minutes fast or slow against clock time through the year. That offset, the equation of time, is what pushes the earliest sunset ahead of the shortest day and the latest sunrise behind it.
| Extreme | Date | Local time | Why then |
|---|---|---|---|
| Earliest sunrise | 16 Jun 2026 | 04:52 | 5 days before the June solstice |
| Latest sunrise | 1 Jan 2026 | 08:41 | 11 days after the December solstice |
| Earliest sunset | 11 Dec 2026 | 16:59 | 10 days before the December solstice |
| Latest sunset | 25 Jun 2026 | 20:55 | 4 days after the June solstice |

That evening stretch is not the same all year in Ulan Bator: it runs from 31 minutes at its shortest, in September, to 41 minutes at its longest, in June. The lower the angle at which the sun crosses the horizon, the longer twilight lasts, which is why dusk is a slow affair at high latitudes and abrupt near the equator.
How high does the sun get in Ulan Bator?

Are the times for Ulan Bator accurate?
Yes. Times are computed with the well established SunCalc astronomy library using the coordinates of Ulan Bator and shown in its local time zone. They are accurate to about a minute for a clear, flat horizon. Hills, tall buildings and atmospheric conditions can shift the moment you actually see the Sun by a few minutes.
