About South Africa Standard Time

South Africa is a fixed UTC+2 and has never used daylight saving. Being in the southern hemisphere, its working day overlaps Europe most comfortably and North America least — and unlike its northern counterparts nothing about that changes through the year.

About Eastern Time

Eastern Time is the most populous North American zone and the one most business hours are quoted in. It is UTC−5 as EST and UTC−4 as EDT. Because it changes on US dates rather than European ones, its gap to London and to Central Europe is not constant — there are two short stretches each year when it is an hour narrower than usual, and they are the reason this pair's table has more than one row.

How the difference is worked out

The gap between South Africa Standard Time and Eastern Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 6 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.

With both zones on their own standard time — daylight saving not in force anywhere — Eastern Time is 7 hours behind South Africa Standard Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.

Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Africa/Johannesburg and America/New_York. Nothing is looked up on a server and nothing about your visit is recorded.
