How to Convert CAT to BST
Converting between Central Africa Time and British Summer Time means accounting for a 1 hour gap — here's how to do it in under 10 seconds with no sign-up.
Pick the date and time in Central Africa Time (UTC +2) that you want to convert. Hit "Now" to load the current CAT time instantly, or use "+1h" to step forward and compare.
The equivalent British Summer Time (UTC +1) time appears immediately. Since BST is 1 hour behind of CAT, most daytime conversions stay on the same calendar day.

Why Choose Our CAT to BST Converter
When someone in South Africa suggests 10:00 AM CAT, that's 9:00 AM BST. This converter shows the overlap so both sides agree on one slot — no back-and-forth.
Late-night CAT times can land on a different date in BST because of the 1 hour offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.
Daylight Saving adjustments can widen or narrow the CAT–BST gap by an hour. During transition weeks many people get it wrong. This converter pulls the current UTC offsets automatically, so the result is right even on the changeover day.
Product launches, sports matches, and webinars are often announced in CAT. Convert the event time to BST so you know exactly when to tune in — with a 1 hour difference, a morning event in South Africa falls during work hours in United Kingdom.
