MST Time Now

Mountain Time is in the MST/MDT time zone (IANA identifier: America/Denver). The current local time is shown in the clock above and updates every second. As part of US, the local UTC offset shifts twice a year if the region observes daylight saving time.

Whether Mountain Time observes DST depends on the local rule for America/Denver. The clock above automatically applies the current DST status, so the displayed time always reflects the actual local time — no manual adjustment needed. Major exceptions worldwide include most of Asia, Iceland, Russia, and parts of Australia, which stay on standard time year-round.

Use our time-zone converter (linked below) — pick Mountain Time as the source and your own city as the destination. The converter handles DST in both zones and shows side-by-side clocks plus the current offset between them.

Computer clocks rely on the operating system's timezone database (typically the IANA tzdata). If your OS has not been updated recently, it may use stale DST rules — common after countries change DST policies (Mexico 2022, parts of Australia 2008). Our clock pulls fresh tzdata and adjusts in real time.
