WET and MST on the World Map
The map below highlights the WET (Western European Time) and MST (Mountain Standard Time) timezone regions across the globe.
WET – Western European Time
UTC+00:00Western European Time (WET) is the time zone for Portugal, Morocco, and the Canary Islands, same as UTC+00:00.
- •Portugal is the only mainland European country in the WET time zone.
- •The Canary Islands are on WET despite being part of Spain (which uses CET).
- •WET is identical to GMT and UTC+00:00.
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.
WET vs MST: Offsets, DST and Best Call Times
WET runs on Western European Time (WET) at UTC+00:00. MST runs on Mountain Standard Time (MST) at UTC-07:00. That puts WET 7 hours behind MST — a difference of -7h at the current offsets.
In practice, when it is 9:00 AM in WET it is 2:00 AM in MST. Midnight in WET is 5:00 PM in MST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert WET to MST time
- Scheduling a call from WET to MST: a 10:00 AM start in WET lands at 3:00 AM in MST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both WET and MST are inside the 9-to-5 working day between 4:00 PM and 5:00 PM WET time (9:00 AM–10:00 AM MST). That is roughly 1 hours of usable overlap.
- Watching a live event or market open: WET viewers need 2:00 AM in MST to catch a 9:00 AM start there, and 7:00 AM if the event is anchored to WET.
- Always state the zone abbreviation, not just the hour. "3:00 PM WET" is unambiguous; "3 PM" across a -7h gap is not.
- Block 4:00 PM–5:00 PM WET as the recurring meeting window if you work primarily from WET and need MST colleagues present.
About WET (Western European Time)
Western European Time (WET) is used in Portugal, the Canary Islands (Spain), Morocco, and several other locations. It is equivalent to GMT/UTC. During summer, Portugal and the Canary Islands switch to WEST (Western European Summer Time, UTC+01:00).
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 WET and MST
Both WET and MST sit inside the 9 AM – 5 PM working day between 4:00 PM–5:00 PM WET, which is 9:00 AM–10:00 AM MST. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
WET and MST overlap for only 60 minutes (4:00 PM–5:00 PM WET), so meetings have to be booked precisely.
WET is 7 hours behind MST (WET UTC+00:00 → MST UTC-07:00). The shared working window is 4:00 PM–5:00 PM WET. Remember to re-check around daylight-saving transitions.
