About EDT to MDT Conversion

Last updated: April 2026

Converting time between EST and MST requires understanding their time zone offsets and any daylight saving time adjustments. EST (EDT) operates at UTC-4, while MST (MDT) is set to UTC-6. This means MST is 2 hours behind EST. For example, when it's 1:22 PM EDT on May 15, 2026, it's 11:22 AM MDT in MST. Both America/New_York and America/Denver observes daylight saving time, switching between EST (UTC-5) and EDT (UTC-4). Keep this in mind when converting times, especially during the spring and fall transition periods. Use this converter to quickly find the equivalent time in MST for any time in EST, whether you're scheduling meetings, planning travel, or coordinating with teams across different time zones.
