Current Time in Ulaanbaatar

Daylight saving time in Ulaanbaatar

Ulaanbaatar does not observe daylight saving time. Its offset stays at UTC+08:00 every day of the year, which makes it one of the simpler zones to work with: a fixed offset is enough to convert any timestamp, and there are no missing or repeated local hours.

Converting timestamps for this zone in code

Always pass the IANA identifier Asia/Ulaanbaatar rather than a numeric offset. The identifier carries the zone's entire history of offset and daylight saving changes, so a timestamp from any year converts correctly; a hard-coded offset is only right until the next rule change.

# Python
from datetime import datetime
from zoneinfo import ZoneInfo
datetime.fromtimestamp(1710050400, ZoneInfo("Asia/Ulaanbaatar"))

// JavaScript
new Intl.DateTimeFormat('en-GB', { timeZone: 'Asia/Ulaanbaatar',
  dateStyle: 'full', timeStyle: 'long' }).format(new Date(1710050400 * 1000));

<?php // PHP
(new DateTimeImmutable("@1710050400"))->setTimezone(new DateTimeZone("Asia/Ulaanbaatar"));
