EET and MST on the World Map
The map below highlights the EET (Eastern European Time) and MST (Mountain Standard Time) timezone regions across the globe.
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.
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.
Understanding the -9h Gap: EET vs MST
EET runs on Eastern European Time (EET) at UTC+02:00. MST runs on Mountain Standard Time (MST) at UTC-07:00. That puts EET 9 hours behind MST — a difference of -9h at the current offsets.
In practice, when it is 9:00 AM in EET it is 12:00 AM in MST. Midnight in EET is 3:00 PM in MST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert EET to MST time
- Scheduling a call from EET to MST: a 10:00 AM start in EET lands at 1:00 AM in MST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: EET and MST 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 MST is 12:00 AM in EET.
- Booking travel or deliveries: tracking MST local time against EET keeps pickup windows and arrival estimates honest across the -9h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM EET" 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 EET takes the early slot, the next week MST does.
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.
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).
Best time to call between EET and MST
With a -9h offset there is no overlap inside a normal 9 AM – 5 PM day. MST opens at 9:00 AM MST, which is 12:00 AM in EET, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
EET and MST have no shared working hours because of the -9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
EET is 9 hours behind MST (EET UTC+02:00 → MST UTC-07:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
