MST and EET on the World Map
The map below highlights the MST (Mountain Standard Time) and EET (Eastern European Time) timezone regions across the globe.
MST – Mountain Standard Time
UTC-07:00Mountain Standard Time (MST) is the time zone for the Mountain region of North America, 7 hours behind UTC.
- •Arizona does not observe daylight saving time, staying on MST year-round.
- •The Navajo Nation in Arizona does observe DST, unlike the rest of the state.
- •Denver, the 'Mile High City', is the largest city fully in MST.
- •MST covers 6 US states entirely and parts of several others.
EET – Eastern European Time
UTC+02:00Eastern European Time (EET) is used in Eastern Europe, the Middle East, and northeastern Africa, 2 hours ahead of UTC.
- •EET covers countries across three continents: Europe, Asia, and Africa.
- •Cairo is the most populous city in the EET zone.
- •Turkey used to be on EET but permanently moved to UTC+03:00 in 2016.
- •Finland, the Baltic states, and Greece all use EET.
Understanding the +9h Gap: MST vs EET
MST runs on Mountain Standard Time (MST) at UTC-07:00. EET runs on Eastern European Time (EET) at UTC+02:00. That puts MST 9 hours ahead of EET — a difference of +9h at the current offsets.
In practice, when it is 9:00 AM in MST it is 6:00 PM in EET. Midnight in MST is 9:00 AM in EET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert MST to EET time
- Scheduling a call from MST to EET: a 10:00 AM start in MST lands at 7:00 PM in EET, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h gap: MST and EET have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in EET is 6:00 PM in MST.
- Watching a live event or market open: MST viewers need 6:00 PM in EET to catch a 9:00 AM start there, and 3:00 PM if the event is anchored to MST.
- Always state the zone abbreviation, not just the hour. "3:00 PM MST" is unambiguous; "3 PM" across a +9h gap is not.
- With a +9h gap there is no shared 9-to-5 window, so alternate the early start: one week MST takes the early slot, the next week EET does.
About MST (Mountain Standard Time)
Mountain Standard Time (MST) covers the Rocky Mountain region of the United States and Canada. Arizona is notable for not observing daylight saving time, staying on MST year-round (except the Navajo Nation). The time zone includes major cities like Denver, Phoenix, Calgary, and Salt Lake City. During summer, most areas switch to Mountain Daylight Time (MDT, UTC-06:00).
About EET (Eastern European Time)
Eastern European Time (EET) covers a wide geographical area including Eastern Europe (Finland, Greece, Romania, Bulgaria, Ukraine), the Middle East (Israel, Lebanon, Jordan), and northeastern Africa (Egypt, Libya). During summer, most EET countries switch to Eastern European Summer Time (EEST, UTC+03:00). Turkey permanently moved to UTC+03:00 in 2016, effectively leaving EET.
Best time to call between MST and EET
With a +9h offset there is no overlap inside a normal 9 AM – 5 PM day. EET opens at 9:00 AM EET, which is 6:00 PM in MST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
MST and EET have no shared working hours because of the +9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
MST is 9 hours ahead of EET (MST UTC-07:00 → EET UTC+02:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
