When the difference changes

West Africa Time and British Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – March 28, 2027British Time is 1 hour behind
  2. March 28, 2027 – October 31, 2027British Time is the same time
  3. October 31, 2027 – onwardsBritish Time is 1 hour behind

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Daylight saving

West Africa Time

No clock changes

West Africa Time stays on WAT all year, so its offset from UTC never moves.

British Time

Sunday, March 28, 2027

Clocks go forward one hour — 1:00 am becomes 2:00 am local time, and the zone is on BST after that.

Scheduling between the two

Working hours overlap from 10:00 am to 6:00 pm WAT, which is 9:00 am to 5:00 pm GMT. Anything inside that window falls in the normal working day at both ends.

A note on BST: it can also mean Bangladesh Standard Time (UTC+6). This page means British Summer Time.

West Africa Time (WAT) is used in Nigeria, Algeria, Angola and Cameroon

British Time (GMT) is used in the whole United Kingdom. In winter the UK is on GMT; from late March to late October it is on BST, an hour ahead.
