- •BST runs from the last Sunday in March to the last Sunday in October.

CET to BST Time Difference – Complete Guide
CET runs on Central European Time (CET) at UTC+01:00. BST runs on British Summer Time (BST) at UTC+01:00. That puts CET no time difference BST — a difference of +0h at the current offsets.
In practice, when it is 9:00 AM in CET it is 9:00 AM in BST. Midnight in CET is 12:00 AM in BST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert CET to BST time
- Scheduling a call from CET to BST: a 10:00 AM start in CET lands at 10:00 AM in BST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both CET and BST are inside the 9-to-5 working day between 9:00 AM and 5:00 PM CET time (9:00 AM–5:00 PM BST). That is roughly 8 hours of usable overlap.
- Coordinating a CET-based team with BST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM CET" is unambiguous; "3 PM" across a +0h gap is not.
- Block 9:00 AM–5:00 PM CET as the recurring meeting window if you work primarily from CET and need BST colleagues present.
About CET (Central European Time)
Central European Time (CET) is the standard time zone for most of Europe, covering over 30 countries from Spain to Poland, and from Norway to Italy. CET is 1 hour ahead of GMT and is used by the European Union's most populous nations. During summer, most CET countries switch to Central European Summer Time (CEST, UTC+02:00). Major European financial markets in Frankfurt, Paris, and Amsterdam operate on CET.
About BST (British Summer Time)
British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.
Best time to call between CET and BST
Both CET and BST sit inside the 9 AM – 5 PM working day between 9:00 AM–5:00 PM CET, which is 9:00 AM–5:00 PM BST. That gives roughly 8 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
CET and BST share 8 hours of working-hours overlap (9:00 AM–5:00 PM CET), so scheduling a live meeting is straightforward.
CET is no time difference BST (CET UTC+01:00 → BST UTC+01:00). The shared working window is 9:00 AM–5:00 PM CET. Remember to re-check around daylight-saving transitions.
