About these time zones
MDT: Mountain Daylight Time
Mountain Daylight Time is UTC−6.
Colorado, Utah, New Mexico, Wyoming, Montana and southern Idaho, plus Alberta, from March to November. Most of Arizona never uses MDT: it stays on MST all year.
EST: Eastern Standard Time
Eastern Standard Time is UTC−5.
New York, Florida, Georgia, the Carolinas, Ohio, Michigan and the rest of the East Coast, plus Ontario and Quebec in Canada. Panama, Jamaica and Cancún stay on EST all year. ET is the short form for the whole zone.
Most places on Eastern Time are on EDT (UTC−4) right now, not EST. People still say "EST" all year, so the times on this page follow the clocks and show EDT until 1 November 2026.
How the difference changes
Both zones change their clocks on the same dates (next on 1 November 2026), so the difference stays 2 hours all year.
