Convert a specific time from MST to EST
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 MST and EST?
Eastern Time is 2 hours ahead of Mountain Time. To go from MST to EST you add 2 hours. 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 MST to EST?
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.
Eastern Time is currently on EDT 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-4 to UTC-5.
Is MST ahead of or behind EST?
MST is behind EST by 2 hours: when it is 12:00 pm in Mountain, it is 2:00 pm in Eastern. 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 est" they nearly always mean the zone rather than the literal winter offset, so this page resolves MST to America/Denver and EST to America/New_York and applies whichever offset is genuinely in force on the day.
Mountain Time covers Denver, Salt Lake City, Albuquerque and Calgary. Eastern Time covers New York, Toronto, Atlanta and Miami. The identifiers behind them are America/Denver and America/New_York, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
