About MMT
Myanmar Time (MMT) is UTC+6:30. It is used in Myanmar, all year.
Myanmar Time is UTC+6:30, another of the half-hour zones and one of only a handful in Asia. It has no daylight saving. The same offset is used by the Cocos Islands, which is the only other place on it, so a UTC+6:30 timestamp is almost always Myanmar.
About MST
Mountain Standard Time (MST) is UTC−7. It is used in Denver and Salt Lake City in winter, and Phoenix all year.
Mountain Standard Time is UTC−7. Denver and Salt Lake City use it in winter and switch to MDT in summer; Arizona does not switch at all and stays on MST year-round, which means Phoenix agrees with Denver in winter and with Los Angeles in summer. The Navajo Nation, inside Arizona, does observe daylight saving, so the state contains both. Any scheduling system that maps "Arizona" to "Mountain Time" without the no-DST flag will be an hour out for eight months.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on MST switches to MDT (UTC−6) from March to November. So the 13.5-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.
MMT does not shift, so the whole change comes from one side. A recurring meeting fixed in MMT will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
Frequently asked questions
What time is 9:00 AM MMT in MST?
9:00 AM MMT is 7:30 PM MST (previous day).
Is MST ahead of MMT?
MST is 13 hours 30 minutes behind MMT.
Which time zone does this use?
MMT is UTC+6:30 and MST is UTC−7. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
