What is MST?
MST means Mountain Standard Time. It is a time zone used in parts of the United States and Canada.
MST is 7 hours behind UTC. This means that UTC is 7 hours ahead of MST.
🕐 Simple Example
Suppose the MST time is:
Add 7 hours:
What happens after midnight?
Sometimes adding 7 hours makes the time move to the next day. When this happens, the date also changes.
MST 8:00 PM → UTC 3:00 AM next day
You do not need to calculate this yourself. The converter automatically shows the correct date.

MST and Daylight Saving Time
There is one important thing to know about Mountain Time. Some places change their clocks during Daylight Saving Time (DST).
During this period, the time may be called MDT (Mountain Daylight Time)instead of MST.
MST is UTC−7, while MDT is UTC−6. Therefore, the difference can change depending on the date and location.
That is why our calculator uses the actual time-zone rules for the selected date instead of simply adding the same number of hours every day.
💡 Easy way to remember
For standard MST:
For example: MST 3:00 PM → UTC 10:00 PM
MST to UTC Formula
The basic formula for standard MST is:
If adding 7 hours takes the time past midnight, the UTC date becomes the next day.
