Abbreviation disambiguation

MST is Mountain Standard Time (UTC−7). Most of the US Mountain zone switches to MDT (UTC−6) in summer, but Arizona (except the Navajo Nation) stays on MST year-round.

On Clockjumper, ET refers to the Eastern Time zone of the United States and Canada. ET is an umbrella name rather than a fixed offset: it means EST (UTC−5) in winter and EDT (UTC−4) in summer, and these pages show whichever is currently in force.

Daylight saving and how the gap changes

The MST → ET offset stays constant across the year — neither zone shifts for daylight saving in a way that changes this gap.

Frequently asked questions

Is ET ahead of or behind MST right now?
ET is currently 2 hours ahead of MST.
What is the current MST to ET time difference?
Right now the gap is 2 hours — ET is 2 hours ahead of MST.
Does the MST → ET offset change during the year?
No. Neither Mountain Standard Time (US) nor Eastern Time (US) shifts for daylight saving in a way that changes this offset — the gap is the same all year.
Does MST observe daylight saving time?
MST is itself the standard-time form. Mountain Standard Time (US) is in force at UTC-7 through the winter months; outside that window the same zone is on MDT (UTC-6).
Does ET observe daylight saving time?
Yes — Eastern Time (US) observes DST, so its UTC offset shifts by 1 hour between winter and summer.

3:00 AM MST is 5:00 AM ET.
What time is 8 AM MST in ET?
