Convert a specific time from CST to MST
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between CST and MST?
Mountain Time is 1 hour behind Central Time. To go from CST to MST you subtract 1 hour. That gap holds on all 365 days of 2026: both zones move their clocks, but on the same dates and in the same direction, so the distance between them never changes.

Does daylight saving change CST to MST?
Central Time is currently on CDT 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-5 to UTC-6.
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.
Is CST ahead of or behind MST?
CST is ahead of MST by 1 hour: when it is 12:00 pm in Central, it is 11:00 am in Mountain. One wrinkle worth knowing: CST and CDT are two names for the same zone, not two zones. Central Time reads CST in winter and CDT in summer. When somebody types "cst to mst" they nearly always mean the zone rather than the literal winter offset, so this page resolves CST to America/Chicago and MST to America/Denver and applies whichever offset is genuinely in force on the day.
Central Time covers Chicago, Dallas, Houston and Winnipeg. Mountain Time covers Denver, Salt Lake City, Albuquerque and Calgary. The identifiers behind them are America/Chicago and America/Denver, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
