Shaded rows are working hours; the darker shade marks the hours when both zones are at work.

What BST and CEST Actually Are

BST — British Summer Time

London, Manchester, Birmingham, Glasgow, and the rest of the UK from late March to late October. Standing at UTC+1:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to GMT. BST also stands for Bangladesh Standard Time (UTC+6). BDT is the clearer label for that one.

British Summer Time began in 1916 as a wartime fuel-saving measure and has run every year since, making it one of the oldest continuous daylight saving schemes in the world.

CEST — Central European Summer Time

Paris, Berlin, Madrid, Rome, Amsterdam, Vienna, Warsaw. Standing at UTC+2:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to CET.

The EU synchronized its daylight saving dates in 1996 so the whole bloc switches on the same weekend, which is why CEST starts and ends everywhere at once.

What This Means in Practice

Both sides change clocks, on different dates

Both regions observe daylight saving but do not switch on the same day, so for a week or two each spring and fall the gap between them is an hour different from the rest of the year. Those short windows are where recurring invitations quietly break.

Close enough to share a working day

At only 1 hour apart, the two working days overlap almost completely. Scheduling is barely constrained by the difference.
