How many hours between MT and UTC?

MT is UTC-7/6 and UTC is UTC+0, a difference of 7 hours. UTC is ahead of MT. This difference can shift by an hour in either direction during Daylight Saving Time transitions — if one zone observes DST and the other doesn't, the offset narrows or widens for part of the year.

Does MT observe Daylight Saving Time?

Mountain Time (MT) is based on the America/Denver IANA timezone. DST observance depends on the jurisdiction — for example, most of the continental US switches between standard and daylight time, while India, Japan, and most of Southeast Asia do not observe DST at all. WorldClock.lol uses the authoritative IANA timezone database, so every conversion automatically accounts for the correct DST rules on the date you're converting.
