WET and HST on the World Map
The map below highlights the WET (Western European Time) and HST (Hawaii 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.
HST – Hawaii Standard Time
UTC-10:00Hawaii Standard Time (HST) is the time zone for the Hawaiian Islands, 10 hours behind UTC.
- •Hawaii does not observe daylight saving time.
- •HST is 5 hours behind EST in winter and 6 hours behind EDT in summer.
- •Hawaii is one of only two US states that don't observe DST (the other is Arizona).
Comparing Time Zones: WET and HST
WET runs on Western European Time (WET) at UTC+00:00. HST runs on Hawaii Standard Time (HST) at UTC-10:00. That puts WET 10 hours behind HST — a difference of -10h at the current offsets.
In practice, when it is 9:00 AM in WET it is 11:00 PM in HST on the previous day. Midnight in WET is 2:00 PM in HST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert WET to HST time
- Scheduling a call from WET to HST: a 10:00 AM start in WET lands at 12:00 AM in HST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -10h gap: WET and HST 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 HST is 11:00 PM in WET.
- Booking travel or deliveries: tracking HST local time against WET keeps pickup windows and arrival estimates honest across the -10h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM WET" is unambiguous; "3 PM" across a -10h gap is not.
- With a -10h gap there is no shared 9-to-5 window, so alternate the early start: one week WET takes the early slot, the next week HST does.
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 HST (Hawaii Standard Time)
Hawaii Standard Time (HST) is used in the state of Hawaii and does not observe daylight saving time. This makes HST one of the most consistent time zones in the US. The Hawaiian Islands are among the last places on Earth to see a new calendar day.
Best time to call between WET and HST
With a -10h offset there is no overlap inside a normal 9 AM – 5 PM day. HST opens at 9:00 AM HST, which is 11:00 PM in WET, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
WET and HST have no shared working hours because of the -10h gap. Teams need to alternate early starts or rely on asynchronous handovers.
WET is 10 hours behind HST (WET UTC+00:00 → HST UTC-10:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
