MDT to EDT converter

When it's 9:00 am in Denver, it's 11:00 am in New York. Your 9-to-5 working days overlap for 6 hours, so there's room for a meeting most days.

Convert Mountain Daylight Time (MDT) to Eastern Daylight Time (EDT) for any date and time.

Eastern Time is 2 hours ahead of Mountain Time all year.

Right now Mountain Time is on MDT (UTC−6) and Eastern Time is on EDT (UTC−4). Both switch back to standard time on 1 November 2026.

US clocks go back on 1 November 2026. From then, EDT is still 2 hours ahead of MDT.

9:00 am to 5:00 pm MDT is 11:00 am to 7:00 pm EDT.

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.

EDT: Eastern Daylight Time

Eastern Daylight Time is UTC−4.

New York, Florida, Georgia, the Carolinas, Ohio, Michigan and the rest of the East Coast, plus Ontario and Quebec, from March to November.

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.
