Converting Mountain Standard Time to Eastern Standard Time
Mountain Standard Time (MST) and Eastern Standard Time (EST) are separated by a 2 hours time difference. EST is 2 hours ahead of MST. MST is UTC-7, used in United States, Canada, while EST is UTC-5, used in United States, Canada, Jamaica.
When converting from MST to EST, the key reference points to remember are: 9:00 AM MST equals 11:00 AM EST, 12:00 PM noon MST equals 2:00 PM EST, and 5:00 PM MST equals 7:00 PM EST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across MST and EST
For professionals scheduling meetings between MST and EST, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 2 hours difference, the window of overlap may be limited. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
MST observes Daylight Saving Time, switching to MDT (UTC-6) during summer months. EST observes DST, switching to EDT (UTC-4). During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
