BST: British Summer Time
British Summer Time
Wednesday, 11th November 2026
What BST actually is
UTC+1, from the last Sunday in March to the last Sunday in October. Outside those dates the UK is on GMT.
Careful: British Summer Time is not on BST at the moment. It is currently GMT (UTC+0) because of daylight saving.
BST means 2 different things
This is the whole reason calendar software uses IANA identifiers instead of abbreviations. All of them, live:
British Summer Time
UTC+1, from the last Sunday in March to the last Sunday in October. Outside those dates the UK is on GMT.
Clocks go forward 1 hour on Sunday, 28th March 2027, at 12:59 am local time (2:00 am after the change).
Bangladesh Standard Time
UTC+6, all year.
Clocks here do not change: this zone stays on the same offset all year.

Why does BST mean more than one time zone?
Time-zone abbreviations were never standardised: several countries independently picked the same letters. BST is one of the worst offenders, with 2 meanings in current use. This is why calendar software and databases use IANA identifiers like Europe/London instead: they are unique, and they carry the daylight-saving rules with them.
