Daylight saving right now

Central Africa Time

Africa/Harare is currently on CAT (UTC+02:00).

no clock change scheduled — this zone is fixed at UTC+02:00

Central Africa Time is UTC+2, fixed, and equal in offset to SAST.

Greenwich Mean Time

Etc/GMT is on GMT (UTC+00:00).

no clock change scheduled — fixed at UTC+00:00

GMT is UTC+0 and never shifts. The UK observes GMT in winter only — in summer it is on BST (UTC+1), so "GMT" on a British invite dated in July usually means BST.

7 overlapping working hours. The longest run is 09:00–16:00 GMT, which is 11:00–18:00 CAT.

GMT to CAT — questions

What time is it in CAT when it is GMT now?
CAT is currently 02:15 on Thursday, 13 August 2026 (CAT, UTC+02:00), while GMT is 00:15 (UTC+00:00). That is 2 hours ahead of the source clock right now.
How many hours ahead is CAT of GMT?
2 hours at this moment. The gap is not constant across the year: Greenwich Mean Time and Central Africa Time change clocks on different dates (or one of them not at all), so a difference you hard-code in summer can be an hour wrong in winter. The table on this page is computed from the current tzdata rules, not from a fixed offset.
Is CAT on daylight saving time right now?
No. Africa/Harare is on CAT (UTC+02:00) at the moment.
Does CAT observe daylight saving time?
No. Africa/Harare stays on UTC+02:00 all year, so the difference from GMT only moves when GMT itself changes.
What is the best time to schedule a call between GMT and CAT?
There are 7 hours of overlap where both sides are inside a 09:00-18:00 working day. The longest block is 09:00–16:00 GMT, which is 11:00–18:00 CAT. Use the calendar buttons above to drop it straight into Google Calendar, Outlook or an .ics file.
Which IANA timezone name should I use for CAT in code?
Use Africa/Harare. Abbreviations like CAT are ambiguous and not resolvable by most libraries — Python's ZoneInfo, Java's ZoneId, Go's time.LoadLocation and JavaScript's Intl all expect the IANA name. Hard-coding UTC+02:00 instead will be wrong the moment the rules change.
