About SAST
South Africa Standard Time (SAST) is UTC+2. It is used in South Africa, Lesotho and Eswatini.
South Africa Standard Time is UTC+2 with no daylight saving, unchanged since 1903 apart from two wartime years. The whole country keeps it, and so do Lesotho and Eswatini. Against the UK it is two hours ahead in winter and one in summer, which is the shift that catches London–Johannesburg standing calls every March and October.
About CDT
Central Daylight Time (CDT) is UTC−5. It is used in Chicago, Dallas and Houston from March to November.
Central Daylight Time is UTC−5, the summer clock for Chicago, Dallas and Houston, from the second Sunday in March to the first Sunday in November. Mexico is the complication: it abolished daylight saving nationally in 2022, so Mexico City stays on UTC−6 all year and is now an hour behind Chicago for eight months of the year rather than matching it.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on CDT switches to CST (UTC−6) from November to March. So the 7-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.
SAST does not shift, so the whole change comes from one side. A recurring meeting fixed in SAST will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
Frequently asked questions
What time is 9:00 AM SAST in CDT?
9:00 AM SAST is 2:00 AM CDT.
Is CDT ahead of SAST?
CDT is 7 hours behind SAST.
Which time zone does this use?
SAST is UTC+2 and CDT is UTC−5. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
