Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.

What are the best hours to schedule a call between HST and WEST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Hawaii and Lisbon are 11 hours apart, which is too far for an overlap, so somebody has to take a call outside their own working day. The least painful options are below, ranked by how close both sides sit to the middle of the afternoon.
| HST | WEST | Working hours | Note |
|---|---|---|---|
| 7:00 am | 6:00 pm | neither side | early morning in Hawaii, evening in Lisbon |
| 8:00 am | 7:00 pm | neither side | mid morning in Hawaii, evening in Lisbon |
Does daylight saving change HST to WEST?
Hawaii Standard Time does not move its clocks at all, so its UTC-10 offset holds every day of the year.
Western European Time is currently on WEST and changes next on Sunday, October 25, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC+1 to UTC+0.
Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is 10 hours and for the rest it is 11 hours. The table above is built for today, not for an average day.
Is HST ahead of or behind WEST?
HST is behind WEST by 11 hours: when it is 12:00 pm in Hawaii, it is 11:00 pm in Lisbon. One wrinkle worth knowing: WET and WEST are two names for the same zone, not two zones. Western European Time reads WET in winter and WEST in summer. When somebody types "hst to wet" they nearly always mean the zone rather than the literal winter offset, so this page resolves HST to Pacific/Honolulu and WET to Europe/Lisbon and applies whichever offset is genuinely in force on the day.
Hawaii Standard Time covers Hawaii, which has never moved its clocks. Western European Time covers Lisbon, Porto and the Canary Islands, one hour behind most of the continent. The identifiers behind them are Pacific/Honolulu and Europe/Lisbon, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
