Frequently Asked Questions
What is the time difference between EDT and CAT?
During standard time, Central Africa Time is 6 hours ahead of Eastern Daylight Time.
When does EDT start and end?
EDT begins on the second Sunday in March at 02:00 local time, when clocks spring forward one hour from EST (UTC-5) to EDT (UTC-4). It ends on the first Sunday in November at 02:00 local time, when clocks fall back to EST. In 2026, EDT runs from March 8 through November 1.
Is EDT the same as EST?
EDT and EST are two phases of the same Eastern Time zone, not two separate zones. EST (Eastern Standard Time) is the winter offset at UTC-5, observed from early November through mid-March. EDT (Eastern Daylight Time) is the summer offset at UTC-4, active during Daylight Saving Time — meaning New York and Toronto run one hour ahead of their winter clock for roughly eight months of every year.
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.
