Frequently Asked Questions
What is the time difference between CAT and CEST?
During standard time, Central European Summer Time is 0 hours ahead of Central Africa Time.
Does the Central Africa Time zone observe Daylight Saving Time?
None of the countries observing Central Africa Time use Daylight Saving Time. South Africa abolished DST in 1994, and no other CAT-observing nation currently applies seasonal clock changes — CAT remains permanently fixed at UTC+02:00 throughout the year.
Which major countries use Central Africa Time (CAT)?
Central Africa Time is observed by South Africa, Zimbabwe, Zambia, Botswana, Mozambique, Malawi, and Eswatini. South Africa is the zone's dominant economy, with Johannesburg functioning as the region's primary financial center and home to the Johannesburg Stock Exchange (JSE), Africa's largest equity market by capitalization.
When does CEST start and end?
CEST begins on the last Sunday in March at 02:00 local CET time, when clocks spring forward one hour from CET (UTC+1) to CEST (UTC+2). It ends on the last Sunday in October at 03:00 local CEST time, when clocks fall back to CET. In 2026, CEST runs from March 29 through October 25, covering approximately seven months of the year across all EU member states that observe this schedule.
Is CEST the same as CET?
CEST and CET are two phases of the same Central European Time zone. CET (Central European Time) is the winter offset at UTC+1, observed from late October through late March. CEST (Central European Summer Time) is the summer offset at UTC+2, active during the EU Daylight Saving Time period — meaning Berlin, Paris, and Rome run one hour ahead of their winter clock for roughly seven months each year.
