What HST and WET Actually Are

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.

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.

What This Means in Practice

The date changes mid-working-day

For 4 of the eight hours in a normal HST working day, the equivalent WET 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.
