MST and WET on the World Map
The map below highlights the MST (Mountain Standard Time) and WET (Western 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.
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.
Time Conversion Guide: MST to WET
MST runs on Mountain Standard Time (MST) at UTC-07:00. WET runs on Western European Time (WET) at UTC+00:00. That puts MST 7 hours ahead of WET — a difference of +7h at the current offsets.
In practice, when it is 9:00 AM in MST it is 4:00 PM in WET. Midnight in MST is 7:00 AM in WET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert MST to WET time
- Scheduling a call from MST to WET: a 10:00 AM start in MST lands at 5:00 PM in WET, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both MST and WET are inside the 9-to-5 working day between 9:00 AM and 10:00 AM MST time (4:00 PM–5:00 PM WET). That is roughly 1 hours of usable overlap.
- Booking travel or deliveries: tracking WET local time against MST keeps pickup windows and arrival estimates honest across the +7h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM MST" is unambiguous; "3 PM" across a +7h gap is not.
- Block 9:00 AM–10:00 AM MST as the recurring meeting window if you work primarily from MST and need WET colleagues present.
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 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).
Best time to call between MST and WET
Both MST and WET sit inside the 9 AM – 5 PM working day between 9:00 AM–10:00 AM MST, which is 4:00 PM–5:00 PM WET. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
MST and WET overlap for only 60 minutes (9:00 AM–10:00 AM MST), so meetings have to be booked precisely.
MST is 7 hours ahead of WET (MST UTC-07:00 → WET UTC+00:00). The shared working window is 9:00 AM–10:00 AM MST. Remember to re-check around daylight-saving transitions.
