About MST and EST
Mountain Time (MST, UTC−7) covers Denver, Salt Lake City, Albuquerque and Calgary (note: most of Arizona stays on MST all year), and observes daylight saving (MST in winter, MDT in summer). Eastern Time (EST, UTC−5) covers New York, Toronto, Miami and Atlanta, and observes daylight saving (EST in winter, EDT in summer).
Because both zones switch to daylight saving on the same dates, the difference stays 2 hours ahead all year round.
