BST: British Time
BST stands for British Time, used in United Kingdom. It runs UTC+0 in the northern winter and UTC+1 in summer, because the clocks change for daylight saving time.
The United Kingdom uses GMT in winter and BST (British Summer Time) in summer. BST also abbreviates Bangladesh Standard Time (UTC+6).
Current BST time
Local times come from your browser's IANA time zone data.
BST time compared with UTC
BST runs UTC+0 in January and UTC+1 in July. When it is 12:00 UTC the clock in BST reads 12:00 in January and 13:00 in July.
| UTC | BST in January | BST in July |
|---|---|---|
| 00:00 | 00:00 | 01:00 |
| 03:00 | 03:00 | 04:00 |
| 06:00 | 06:00 | 07:00 |
| 09:00 | 09:00 | 10:00 |
| 12:00 | 12:00 | 13:00 |
| 15:00 | 15:00 | 16:00 |
| 18:00 | 18:00 | 19:00 |
| 21:00 | 21:00 | 22:00 |
When the clocks change in the BST zone
Clocks in the BST zone change twice a year for daylight saving time. Each row gives the date, the reading the clock shows as it changes, and what it jumps to.
| Date | Change | Clocks | New offset |
|---|---|---|---|
| Sunday, March 29, 2026 | Forward one hour | 01:00 to 02:00 | UTC+1 |
| Sunday, October 25, 2026 | Back one hour | 02:00 to 01:00 | UTC+0 |
| Sunday, March 28, 2027 | Forward one hour | 01:00 to 02:00 | UTC+1 |
| Sunday, October 31, 2027 | Back one hour | 02:00 to 01:00 | UTC+0 |
Computed from the IANA time zone database, the same source your operating system uses. Dates in future years follow the rules in force today; daylight saving law is set by governments and does change, sometimes at a few months' notice.
