UTC to BST — questions

What time is it in BST when it is UTC now?
BST is currently 00:21 on Thursday, 13 August 2026 (BST, UTC+01:00), while UTC is 23:21 (UTC+00:00). That is 1 hours ahead of the source clock right now.
How many hours ahead is BST of UTC?
1 hours at this moment. The gap is not constant across the year: Coordinated Universal Time and British Summer Time change clocks on different dates (or one of them not at all), so a difference you hard-code in summer can be an hour wrong in winter. The table on this page is computed from the current tzdata rules, not from a fixed offset.
Is BST on daylight saving time right now?
Yes — Europe/London is on BST (UTC+01:00) right now.
When does BST next change its clocks?
Europe/London next changes on Sunday, 25 October 2026 at 01:00 local time, when it moves back 60 minutes and the abbreviation becomes GMT (UTC+00:00). That is 73 days away. This date comes from the IANA tzdata rules currently in force, so it updates if a government changes the law.
What is the best time to schedule a call between UTC and BST?
There are 8 hours of overlap where both sides are inside a 09:00-18:00 working day. The longest block is 09:00–17:00 UTC, which is 10:00–18:00 BST. Use the calendar buttons above to drop it straight into Google Calendar, Outlook or an .ics file.
Which IANA timezone name should I use for BST in code?
Use Europe/London. Abbreviations like BST are ambiguous and not resolvable by most libraries — Python's ZoneInfo, Java's ZoneId, Go's time.LoadLocation and JavaScript's Intl all expect the IANA name. Hard-coding UTC+01:00 instead will be wrong the moment the rules change.
