Why people convert BST to WET time
- Scheduling a call from BST to WET: a 10:00 AM start in BST lands at 9:00 AM in WET, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both BST and WET are inside the 9-to-5 working day between 10:00 AM and 5:00 PM BST time (9:00 AM–4:00 PM WET). That is roughly 7 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in BST is 7:00 PM in WET 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 10:00 AM–5:00 PM BST as the recurring meeting window if you work primarily from BST and need WET 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 WET (Western European Time)
Western European Time (WET) is used in Portugal, the Canary Islands (Spain), Morocco, and several other locations. It is equivalent to GMT/UTC. During summer, Portugal and the Canary Islands switch to WEST (Western European Summer Time, UTC+01:00).
Best time to call between BST and WET
Both BST and WET sit inside the 9 AM – 5 PM working day between 10:00 AM–5:00 PM BST, which is 9:00 AM–4:00 PM WET. That gives roughly 7 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
BST and WET share 7 hours of working-hours overlap (10:00 AM–5:00 PM BST), so scheduling a live meeting is straightforward.
BST is 1 hour behind WET (BST UTC+01:00 → WET UTC+00:00). The shared working window is 10:00 AM–5:00 PM BST. Remember to re-check around daylight-saving transitions.
