CET and MST on the World Map
The map below highlights the CET (Central European Time) and MST (Mountain Standard Time) timezone regions across the globe.
CET – Central European Time
UTC+01:00Central European Time (CET) is used across most of Western and Central Europe, 1 hour ahead of UTC.
- •CET covers more European countries than any other time zone.
- •Spain uses CET despite being geographically aligned with GMT/WET.
- •The Frankfurt Stock Exchange, Euronext (Amsterdam/Paris), and Borsa Italiana operate on CET.
- •Over 500 million people live in the CET time zone.
- •France moved to CET during the German occupation in WWII and never switched back.
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.
CET vs MST: Offsets, DST and Best Call Times
CET runs on Central European Time (CET) at UTC+01:00. MST runs on Mountain Standard Time (MST) at UTC-07:00. That puts CET 8 hours behind MST — a difference of -8h at the current offsets.
In practice, when it is 9:00 AM in CET it is 1:00 AM in MST. Midnight in CET is 4:00 PM in MST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert CET to MST time
- Scheduling a call from CET to MST: a 10:00 AM start in CET lands at 2:00 AM in MST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: CET 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 1:00 AM in CET.
- Coordinating a CET-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 CET" is unambiguous; "3 PM" across a -8h gap is not.
- With a -8h gap there is no shared 9-to-5 window, so alternate the early start: one week CET takes the early slot, the next week MST does.
About CET (Central European Time)
Central European Time (CET) is the standard time zone for most of Europe, covering over 30 countries from Spain to Poland, and from Norway to Italy. CET is 1 hour ahead of GMT and is used by the European Union's most populous nations. During summer, most CET countries switch to Central European Summer Time (CEST, UTC+02:00). Major European financial markets in Frankfurt, Paris, and Amsterdam operate on CET.
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 CET and MST
With a -8h offset there is no overlap inside a normal 9 AM – 5 PM day. MST opens at 9:00 AM MST, which is 1:00 AM in CET, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
CET and MST have no shared working hours because of the -8h gap. Teams need to alternate early starts or rely on asynchronous handovers.
CET is 8 hours behind MST (CET UTC+01:00 → 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.
