WET to HST Time Converter

HST is 11 hours behind WET. Portugal and the Canary Islands are currently on WEST (UTC+1:00), and HST is UTC-10:00.

Worth knowing right now. Portugal and the Canary Islands are currently on WEST, not WET, because daylight saving is in effect. The 11 hours above is the gap between those two regions today, which is almost certainly what you want. Taken strictly as written, WET to HST is 10 hours.

Best Time to Call Between WET and HST

Standard 9-to-5 hours in these two zones never overlap, so someone has to take the call outside their working day. The most workable window is 6:00 PM to 10:00 PM WET, which is 7:00 AM to 11:00 AM HST.

What WET and HST Actually Are

WET — Western European Time

Lisbon, Porto, the Canary Islands. Standing at UTC as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to WET.

Portugal moved to Central European Time in 1992 and switched back four years later, after finding that later sunrises hurt more than later sunsets helped.

HST — Hawaii Standard Time

Honolulu and the rest of Hawaii. Standing at UTC-10:00 as written, and the region does not change its clocks, so that offset holds all year. Hawaii does not observe daylight saving, so this offset holds all year.

Hawaii dropped daylight saving in 1967 and never resumed it. Being close to the equator, its daylight barely varies across the year, so there is little to gain.

What This Means in Practice

The date changes mid-working-day

For 2 of the eight hours in a normal WET working day, the equivalent HST time falls on a different calendar date. Anything scheduled in that stretch needs the date checked as well as the time, or a Tuesday call quietly becomes a Wednesday one at the other end.

This gap is not fixed

WET changes its clocks and HST does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, October 25, 2026 unless someone resets it.

Nearly opposite sides of the clock

At 11 hours apart, one side's morning is the other side's night. Handing work over at the end of a shift usually beats trying to get both parties in the same call.

Frequently Asked Questions

What is the time difference between WET and HST?

HST is 11 hours behind WET. That is the live figure. Taken strictly as written, the gap between WET and HST is 10 hours — the two differ because at least one of these regions is currently on daylight saving.

What is 9:00 AM WET in HST?

9:00 AM WET is 10:00 PM the previous day HST.

What are the best hours to schedule a call between WET and HST?

Standard business hours in these two zones do not overlap at all, so one side has to work outside the 9-to-5. The most workable window is 6:00 PM to 10:00 PM WET, which is 7:00 AM to 11:00 AM HST.

Does the difference between WET and HST change during the year?

Yes. WET observes daylight saving and HST does not, so the gap shifts by an hour at least twice a year. The next clock change is on Sunday, October 25, 2026.

Does HST always mean Hawaii Standard Time?

Hawaii does not observe daylight saving, so this offset holds all year.
