BST and CEST on the World Map
The map below highlights the BST (British Summer Time) and CEST (Central European Summer Time) timezone regions across the globe.
BST – British Summer Time
UTC+01:00British Summer Time (BST, UTC+01:00) is the daylight saving period in the United Kingdom, running from late March to late October.
- •BST runs from the last Sunday in March to the last Sunday in October.
- •BST is exactly one hour ahead of GMT, the UK's standard time.
- •During BST, London is 4 hours ahead of New York while the US is on Eastern Daylight Time.
- •The Isle of Man and the Channel Islands also observe BST.
CEST – Central European Summer Time
UTC+02:00Central European Summer Time (CEST) is the daylight saving time in Central Europe, 2 hours ahead of UTC.
- •CEST runs from the last Sunday of March to the last Sunday of October.
- •The EU has voted to abolish clock changes but implementation has been delayed.
- •CEST shares the same offset as EET (UTC+02:00).
BST vs CEST: Offsets, DST and Best Call Times
BST runs on British Summer Time (BST) at UTC+01:00. CEST runs on Central European Summer Time (CEST) at UTC+02:00. That puts BST 1 hour ahead of CEST — a difference of +1h at the current offsets.
In practice, when it is 9:00 AM in BST it is 10:00 AM in CEST. Midnight in BST is 1:00 AM in CEST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert BST to CEST time
- Scheduling a call from BST to CEST: a 10:00 AM start in BST lands at 11:00 AM in CEST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both BST and CEST are inside the 9-to-5 working day between 9:00 AM and 4:00 PM BST time (10:00 AM–5:00 PM CEST). That is roughly 7 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in BST is 9:00 PM in CEST makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM BST" is unambiguous; "3 PM" across a +1h gap is not.
- Block 9:00 AM–4:00 PM BST as the recurring meeting window if you work primarily from BST and need CEST colleagues present.
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.
About CEST (Central European Summer Time)
Central European Summer Time (CEST) is observed from the last Sunday of March to the last Sunday of October across most of Europe. During CEST, clocks are 2 hours ahead of UTC. The EU has debated abolishing seasonal clock changes since 2019.
Best time to call between BST and CEST
Both BST and CEST sit inside the 9 AM – 5 PM working day between 9:00 AM–4:00 PM BST, which is 10:00 AM–5:00 PM CEST. That gives roughly 7 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
BST and CEST share 7 hours of working-hours overlap (9:00 AM–4:00 PM BST), so scheduling a live meeting is straightforward.
BST is 1 hour ahead of CEST (BST UTC+01:00 → CEST UTC+02:00). The shared working window is 9:00 AM–4:00 PM BST. Remember to re-check around daylight-saving transitions.
