Convert a specific time from BST to HST
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 BST and HST?
Hawaii Standard Time is 11 hours behind UK Time. To go from BST to HST you subtract 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.
BST to HST conversion table
Every hour of Friday, September 25, 2026 in UK, with the matching reading in Hawaii. 11 of the 24 hours land on a different calendar date in Hawaii, which is the part people get wrong when they schedule across this pair.

What are the best hours to schedule a call between BST and HST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. UK and Hawaii 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.
| BST | HST | Working hours | Note |
|---|---|---|---|
| 6:00 pm | 7:00 am | neither side | evening in UK, early morning in Hawaii |
| 7:00 pm | 8:00 am | neither side | evening in UK, mid morning in Hawaii |
Does daylight saving change BST to HST?
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.
Hawaii Standard Time does not move its clocks at all, so its UTC-10 offset holds every day of the year.
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 BST ahead of or behind HST?
BST is ahead of HST by 11 hours: when it is 12:00 pm in UK, it is 1:00 am in Hawaii. 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 "bst to hst" they nearly always mean the zone rather than the literal winter offset, so this page resolves BST to Europe/London and HST to Pacific/Honolulu and applies whichever offset is genuinely in force on the day.
UK Time covers London, Cardiff, Edinburgh and Dublin. Hawaii Standard Time covers Hawaii, which has never moved its clocks. The identifiers behind them are Europe/London and Pacific/Honolulu, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
