Questions about MST and BST time
What is the time difference between MST and BST?
The current difference is shown at the top of this page. MST uses Mountain Standard Time (MST, UTC−7) as standard time and Mountain Daylight Time (MDT, UTC−6) during daylight saving time; BST uses Greenwich Mean Time (GMT, UTC+0) as standard time and British Summer Time (BST, UTC+1) during daylight saving time. The difference can change if only one side observes daylight saving time or if their clocks change on different dates. Choose your meeting date in the converter to check the applicable offset.
