About MST and EST

MST is UTC−7. EST is UTC−5. The two-hour gap is the winter reading of America/Denver and America/New_York. In summer the same places are MDT (UTC−6) and EDT (UTC−4), and Denver is still two hours behind New York.

The Mountain Time to EST page covers the general zone name. This page answers searches that use the letters MST. Arizona’s year-round MST is not Denver: in summer Phoenix is three hours behind New York.

Standard and daylight labels. The converter reads IANA for the date you pick. It does not add these offsets by hand.
Zone	IANA	Standard	Daylight
Mountain Time	`America/Denver`	MST (UTC−7)	MDT (UTC−6)
Eastern Time	`America/New_York`	EST (UTC−5)	EDT (UTC−4)
