What is WET in MST?

Mountain Time is 7 hours behind

Western European Time is on UTC+1:00 and Mountain Time is on UTC−6:00 right now. Both are on daylight saving, so their clocks read WEST and MDT. The gap changes during the year — see below.

When the difference changes

Western European Time and Mountain Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  2. October 25, 2026November 1, 2026Mountain Time is 6 hours behind

Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.

Scheduling between the two

Working hours overlap from 4:00 pm to 6:00 pm WEST, which is 9:00 am to 11:00 am MDT. Anything inside that window falls in the normal working day at both ends.

Western European Time (WEST) is used in Portugal, Ireland and the Canary Islands

Mountain Time (MDT) is used in Salt Lake City, Albuquerque and Calgary. Arizona keeps MST all year and does not follow MDT.
