Does daylight saving change MDT to WEST?
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.
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.
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 MDT ahead of or behind WEST?
MDT is behind WEST by 7 hours: when it is 12:00 pm in Mountain, it is 7:00 pm in Lisbon. One wrinkle worth knowing: MST and MDT are two names for the same zone, not two zones. Mountain Time reads MST in winter and MDT in summer. When somebody types "mst to wet" they nearly always mean the zone rather than the literal winter offset, so this page resolves MST to America/Denver and WET to Europe/Lisbon and applies whichever offset is genuinely in force on the day.
Mountain Time covers Denver, Salt Lake City, Albuquerque and Calgary. Western European Time covers Lisbon, Porto and the Canary Islands, one hour behind most of the continent. The identifiers behind them are America/Denver and Europe/Lisbon, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
