HST to WET Time Difference – Complete Guide
HST runs on Hawaii Standard Time (HST) at UTC-10:00. WET runs on Western European Time (WET) at UTC+00:00. That puts HST 10 hours ahead of WET — a difference of +10h at the current offsets.

Why people convert HST to WET time
- Scheduling a call from HST to WET: a 10:00 AM start in HST lands at 8:00 PM in WET, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +10h gap: HST and WET 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 WET is 7:00 PM in HST.
- Watching a live event or market open: HST viewers need 7:00 PM in WET to catch a 9:00 AM start there, and 2:00 PM if the event is anchored to HST.
- Always state the zone abbreviation, not just the hour. "3:00 PM HST" 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 HST takes the early slot, the next week WET does.
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.
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 HST and WET
With a +10h offset there is no overlap inside a normal 9 AM – 5 PM day. WET opens at 9:00 AM WET, which is 7:00 PM in HST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
HST and WET have no shared working hours because of the +10h gap. Teams need to alternate early starts or rely on asynchronous handovers.
HST is 10 hours ahead of WET (HST UTC-10:00 → WET UTC+00:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
