Converting MST to EST
To convert Mountain Standard Time to Eastern Standard Time, add 2 hours — Eastern always runs ahead of Mountain. So 9:00 AM MST is 11:00 AM EST, and 3:00 PM MST is 5:00 PM EST. The live clocks and conversion table above and below do this for you automatically, using the official timezone rules so daylight saving is always already applied.
What Is the Time Difference Between MST and EST?
Eastern Time is 2 hours ahead of Mountain Time. Because both zones follow the same US daylight saving schedule, that 2-hour gap stays constant all year: when Mountain switches to MDT in summer, Eastern switches to EDT at the same time, so Eastern remains exactly 2 hours ahead. The current difference is shown live under the clocks above.

Mountain and Eastern Time Zones
MST — Mountain Standard Time (UTC−7 standard, UTC−6 as MDT in summer) covers Denver, Salt Lake City, and Albuquerque.
EST — Eastern Standard Time (UTC−5 standard, UTC−4 as EDT in summer) covers New York, Toronto, and Miami.
Both zones observe daylight saving on the same US schedule, so the gap between them stays constant all year — in summer the abbreviations become MDT and EDT, but Eastern stays 2 hours ahead of Mountain.
