Current time in MDT
MDT is UTC-6, used across US mountain states. The clock below runs at that offset rather than at any one city's local time, because an abbreviation names an offset: when the region switches for the summer, the city moves and MDT stays where it is.

How it works
The offset comes from the IANA time zone database rather than a table we typed out, read through the America/Denver entry, so it follows the same data your operating system uses and cannot drift out of date on its own.
MDT and MST are the two halves of the same region's year. Clocks move between them on the changeover dates; the offsets themselves never move.
Frequently asked questions
Does MDT change with daylight saving?
No. MDT is always UTC-6; what changes is which regions are using it. US mountain states switches to its other abbreviation for part of the year, and a clock in that region moves with the switch while MDT stays put.
Does MDT mean only one thing?
Here, yes: these letters map to one offset, UTC-6, used by US mountain states. That is not true of every abbreviation, which is why the safe habit for scheduling is to write the offset or the IANA zone name alongside the letters.
How do I convert a meeting time into MDT?
Use the timezone converter linked above: pick the source zone and read the result. Doing it in your head is where mistakes come from, because you have to remember both sides' switch dates as well as the offsets, and the two hemispheres do not switch on the same weekends.
