Mountain Time

Mountain Time refers to a time zone in the United States that includes CSU in Fort Collins, Colorado. The current Mountain Time is 10:03ᴀᴍ MDT on Friday May 17.

There are several variations:

• Mountain Daylight Time (MDT) is when Daylight Saving Time is observed, between the second Sunday in March and the first Sunday in November.
• Mountain Standard Time (MST) is the rest of the year.
• Mountain Time (MT) is either of the two, depending on the date. It’s MDT now.

Fun facts:

• The “Standard” in “Mountain Standard Time” does not mean “official”, it means “non‑daylight‑saving”.
• It’s “Saving”, not “Savings”.
• There is rarely any benefit to using the terms MDT or MST, and it’s annoying when they’re misused. Write MT and be done with it.
