CST and CAT on the World Map
The map below highlights the CST (Central Standard Time) and CAT (Central Africa Time) timezone regions across the globe.
CST – Central Standard Time
UTC-06:00Central Standard Time (CST) is the time zone for the central United States, Canada, and Mexico, 6 hours behind UTC.
- •CST covers 20 US states fully or partially.
- •Chicago and Houston are the two largest cities in the Central Time Zone.
- •Mexico City, one of the world's most populous cities, operates on CST.
- •CST is 1 hour behind EST and 2 hours ahead of PST.
CAT – Central Africa Time
UTC+02:00Central Africa Time (CAT, UTC+02:00) covers Zimbabwe, Zambia, Mozambique, Malawi and neighbouring countries.
- •Central Africa Time is fixed at UTC+02:00 with no daylight saving.
- •CAT matches South Africa Standard Time (SAST) all year.
- •It is the same offset as Central European Time in winter.
- •Harare is level with Johannesburg and one hour ahead of Lagos.
Understanding the +8h Gap: CST vs CAT
CST runs on Central Standard Time (CST) at UTC-06:00. CAT runs on Central Africa Time (CAT) at UTC+02:00. That puts CST 8 hours ahead of CAT — a difference of +8h at the current offsets.
In practice, when it is 9:00 AM in CST it is 5:00 PM in CAT. Midnight in CST is 8:00 AM in CAT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert CST to CAT time
- Scheduling a call from CST to CAT: a 10:00 AM start in CST lands at 6:00 PM in CAT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +8h gap: CST and CAT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in CAT is 5:00 PM in CST.
- Booking travel or deliveries: tracking CAT local time against CST keeps pickup windows and arrival estimates honest across the +8h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM CST" is unambiguous; "3 PM" across a +8h gap is not.
- With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week CST takes the early slot, the next week CAT does.
About CST (Central Standard Time)
Central Standard Time (CST) covers the central region of North America. It is the second most populous time zone in the US, including major cities like Chicago, Houston, and Dallas. CST is also used in Mexico City and much of Central America including Guatemala, Honduras, El Salvador, and Costa Rica. During summer, most of the US and Canada switch to Central Daylight Time (CDT, UTC-05:00), while Mexico and Central American countries generally remain on CST.
About CAT (Central Africa Time)
Central Africa Time (CAT) is fixed at UTC+02:00 all year across a broad belt of southern and central Africa, including Zimbabwe, Zambia, Mozambique, Malawi, Rwanda, Burundi and the eastern Democratic Republic of the Congo. None of these countries observes daylight saving time, so CAT never shifts. It is the same offset as South Africa Standard Time (SAST) and the winter version of Central European Time, which makes CAT a convenient bridge between African, European and Middle Eastern schedules — Harare is level with Johannesburg all year and one hour ahead of Lagos.
Best time to call between CST and CAT
With a +8h offset there is no overlap inside a normal 9 AM – 5 PM day. CAT opens at 9:00 AM CAT, which is 5:00 PM in CST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
CST and CAT have no shared working hours because of the +8h gap. Teams need to alternate early starts or rely on asynchronous handovers.
CST is 8 hours ahead of CAT (CST UTC-06:00 → CAT UTC+02:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
