BST — British Summer Time
British Summer Time
Thursday, 13th August 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.
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 back 1 hour on Sunday, 25th October 2026, at 1:59 am local time (1:00 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.
