SAST and CDT on the World Map
The map below highlights the SAST (South Africa Standard Time) and CDT (Central Daylight Time) timezone regions across the globe.
SAST – South Africa Standard Time
UTC+02:00South Africa Standard Time (SAST) is the time zone for South Africa and neighboring countries, 2 hours ahead of UTC.
- •South Africa does not observe daylight saving time.
- •SAST is the same offset as EET and Israel Standard Time.
- •The Johannesburg Stock Exchange (JSE) is Africa's largest.
CDT – Central Daylight Time
UTC-05:00Central Daylight Time (CDT) is the daylight saving offset in the Central Time Zone, 5 hours behind UTC.
- •CDT is the same offset as EST (UTC-05:00), which can cause confusion.
- •CDT runs from the second Sunday in March to the first Sunday in November.
Understanding the -7h Gap: SAST vs CDT
SAST runs on South Africa Standard Time (SAST) at UTC+02:00. CDT runs on Central Daylight Time (CDT) at UTC-05:00. That puts SAST 7 hours behind CDT — a difference of -7h at the current offsets.
In practice, when it is 9:00 AM in SAST it is 2:00 AM in CDT. Midnight in SAST is 5:00 PM in CDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert SAST to CDT time
- Scheduling a call from SAST to CDT: a 10:00 AM start in SAST lands at 3:00 AM in CDT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both SAST and CDT are inside the 9-to-5 working day between 4:00 PM and 5:00 PM SAST time (9:00 AM–10:00 AM CDT). That is roughly 1 hours of usable overlap.
- Coordinating a SAST-based team with CDT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM SAST" is unambiguous; "3 PM" across a -7h gap is not.
- Block 4:00 PM–5:00 PM SAST as the recurring meeting window if you work primarily from SAST and need CDT colleagues present.
About SAST (South Africa Standard Time)
South Africa Standard Time (SAST) is used in South Africa, Lesotho, and Eswatini. SAST does not observe daylight saving time. Johannesburg and Cape Town are major economic hubs in Africa.
About CDT (Central Daylight Time)
Central Daylight Time (CDT) is observed during summer months in the US and Canadian portions of the Central Time Zone. Clocks are moved forward by one hour, aligning with Eastern Standard Time (EST). Most of Mexico and Central America do not observe CDT, staying on CST year-round.
Best time to call between SAST and CDT
Both SAST and CDT sit inside the 9 AM – 5 PM working day between 4:00 PM–5:00 PM SAST, which is 9:00 AM–10:00 AM CDT. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
SAST and CDT overlap for only 60 minutes (4:00 PM–5:00 PM SAST), so meetings have to be booked precisely.
SAST is 7 hours behind CDT (SAST UTC+02:00 → CDT UTC-05:00). The shared working window is 4:00 PM–5:00 PM SAST. Remember to re-check around daylight-saving transitions.
