CEST and MST on the World Map
The map below highlights the CEST (Central European Summer Time) and MST (Mountain Standard Time) timezone regions across the globe.
CEST – Central European Summer Time
UTC+02:00Central European Summer Time (CEST) is the daylight saving time in Central Europe, 2 hours ahead of UTC.
- •CEST runs from the last Sunday of March to the last Sunday of October.
- •The EU has voted to abolish clock changes but implementation has been delayed.
- •CEST shares the same offset as EET (UTC+02:00).
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.
Everything You Need to Know About CEST and MST Time
CEST runs on Central European Summer Time (CEST) at UTC+02:00. MST runs on Mountain Standard Time (MST) at UTC-07:00. That puts CEST 9 hours behind MST — a difference of -9h at the current offsets.
In practice, when it is 9:00 AM in CEST it is 12:00 AM in MST. Midnight in CEST is 3:00 PM in MST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert CEST to MST time
- Scheduling a call from CEST to MST: a 10:00 AM start in CEST lands at 1:00 AM in MST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: CEST 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 CEST.
- Coordinating a CEST-based team with MST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM CEST" 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 CEST takes the early slot, the next week MST does.
About CEST (Central European Summer Time)
Central European Summer Time (CEST) is observed from the last Sunday of March to the last Sunday of October across most of Europe. During CEST, clocks are 2 hours ahead of UTC. The EU has debated abolishing seasonal clock changes since 2019.
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 CEST 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 CEST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
CEST and MST have no shared working hours because of the -9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
CEST is 9 hours behind MST (CEST 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.
