Why people convert London to WET time
- Scheduling a call from London to WET: a 10:00 AM start in London lands at 9:00 AM in WET, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both London 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.
- Watching a live event or market open: London viewers need 8:00 AM in WET to catch a 9:00 AM start there, and 1:00 AM if the event is anchored to London.
- 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 London and need WET colleagues present.
- London: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -1h gap.

GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.
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).
