Frequently Asked Questions

What is the time difference between MDT and MSK?

During standard time, Moscow Standard Time is 9 hours ahead of Mountain Daylight Time.

When does MDT start and end?

MDT begins on the second Sunday in March at 02:00 local MST time, when clocks spring forward one hour from MST (UTC-7) to MDT (UTC-6). It ends on the first Sunday in November at 02:00 local MDT time, when clocks fall back to MST. In 2026, MDT runs from March 8 through November 1, covering the majority of the calendar year.

Is Arizona on MDT?

Most of Arizona — including Phoenix and Tucson — does not observe Daylight Saving Time and remains on MST (UTC-7) year-round under a state law in effect since 1968, meaning Arizona does not advance to MDT each March. The significant exception is the Navajo Nation, a sovereign territory spanning parts of northeastern Arizona, southeastern Utah, and northwestern New Mexico, which does observe DST and shifts to MDT on the standard federal schedule.

Does Russia observe Daylight Saving Time?

Russia abolished Daylight Saving Time entirely in 2014, settling permanently on standard time after a contentious experiment with year-round summer time that began in 2011. Moscow Standard Time has remained fixed at UTC+03:00 ever since, with no seasonal clock changes of any kind.

Are MSK and Eastern European Summer Time (EEST) the same?

During summer, countries observing Eastern European Time — including Ukraine, Romania, and Greece — shift to EEST at UTC+03:00, which numerically matches MSK exactly. However, MSK holds at UTC+03:00 year-round, while EEST is a temporary designation that reverts to UTC+02:00 when those countries return to standard time each autumn.
