Convert a specific time from HST to BST
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 is the time difference between HST and BST?
UK Time is 11 hours ahead of Hawaii Standard Time. To go from HST to BST you add 11 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 10 hours to 11 hours, because UK moves its clocks and Hawaii does not. This page recomputes it rather than assuming.

What are the best hours to schedule a call between HST and BST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Hawaii and UK 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 | BST | Working hours | Note |
|---|---|---|---|
| 7:00 am | 6:00 pm | neither side | early morning in Hawaii, evening in UK |
| 8:00 am | 7:00 pm | neither side | mid morning in Hawaii, evening in UK |
Does daylight saving change HST to BST?
Hawaii Standard Time does not move its clocks at all, so its UTC-10 offset holds every day of the year.
UK Time is currently on BST 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 BST?
HST is behind BST by 11 hours: when it is 12:00 pm in Hawaii, it is 11:00 pm in UK. One wrinkle worth knowing: GMT and BST are two names for the same zone, not two zones. UK Time reads GMT in winter and BST in summer. When somebody types "hst to bst" they nearly always mean the zone rather than the literal winter offset, so this page resolves HST to Pacific/Honolulu and BST to Europe/London and applies whichever offset is genuinely in force on the day.
Hawaii Standard Time covers Hawaii, which has never moved its clocks. UK Time covers London, Cardiff, Edinburgh and Dublin. The identifiers behind them are Pacific/Honolulu and Europe/London, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
