Does daylight saving change WEST to MDT?
Western European Time is currently on WEST and changes next on Sunday, October 25, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC+1 to UTC+0.
Mountain Time is currently on MDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-6 to UTC-7.
Because the two sides do not move together, the answer to this conversion changes during the year. The United States changes on the second Sunday in March and the first Sunday in November, while the United Kingdom and European Union change on the last Sunday in March and the last Sunday in October. Those dates are weeks apart, which opens a window each spring and autumn where the usual gap is an hour out. The table above is built for today, not for an average day.
Is WEST ahead of or behind MDT?
WEST is ahead of MDT by 7 hours: when it is 12:00 pm in Lisbon, it is 5:00 am in Mountain. One wrinkle worth knowing: WET and WEST are two names for the same zone, not two zones. Western European Time reads WET in winter and WEST in summer. When somebody types "wet to mst" they nearly always mean the zone rather than the literal winter offset, so this page resolves WET to Europe/Lisbon and MST to America/Denver and applies whichever offset is genuinely in force on the day.
Western European Time covers Lisbon, Porto and the Canary Islands, one hour behind most of the continent. Mountain Time covers Denver, Salt Lake City, Albuquerque and Calgary. The identifiers behind them are Europe/Lisbon and America/Denver, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
