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.
About NPT
Nepal Time (NPT) is UTC+5:45. It is used in Nepal, all year.
Nepal Time is UTC+5:45 — the only zone in the world offset by three quarters of an hour, set so that noon falls over Kathmandu rather than over the Indian meridian fifteen minutes away. It breaks almost every piece of software that stores offsets in whole or half hours, and it is fifteen minutes ahead of India rather than the round number people assume.
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 12.75-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.
NPT does not shift, so the whole change comes from one side. A recurring meeting fixed in NPT 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 MST in NPT?
9:00 AM MST is 9:45 PM NPT.
Is NPT ahead of MST?
NPT is 12 hours 45 minutes ahead of MST.
Which time zone does this use?
MST is UTC−7 and NPT is UTC+5:45. 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.
