Frequently Asked Questions
What is the time difference between NZST and CAT?
During standard time, Central Africa Time is 10 hours behind New Zealand Standard Time.
Does New Zealand observe Daylight Saving Time?
New Zealand observes Daylight Saving Time annually, advancing clocks to New Zealand Daylight Time (NZDT) at UTC+13:00 on the last Sunday of September and returning to NZST (UTC+12:00) on the first Sunday of April. In 2026, clocks spring forward on September 27 and fall back on April 5 — following the Southern Hemisphere calendar, which runs opposite to DST schedules in Europe and North America.
Why does Antarctica use New Zealand Time?
McMurdo Station and Amundsen-Scott South Pole Station — the two largest US Antarctic research bases — operate on NZST and NZDT because their primary supply and personnel flights operate out of Christchurch International Airport in New Zealand. Aligning base operations with New Zealand time eliminates scheduling complexity across the Christchurch–McMurdo logistics chain, which handles all cargo, fuel, and personnel rotations for the US Antarctic Program.
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.
