Why people convert CAT to MST time
- Scheduling a call from CAT to MST: a 10:00 AM start in CAT lands at 1:00 AM in MST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: CAT and MST 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 MST is 12:00 AM in CAT.
- Keeping family and friends in sync: knowing that 8:00 PM in CAT is 11:00 AM in MST makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM CAT" is unambiguous; "3 PM" across a -9h gap is not.
- With a -9h gap there is no shared 9-to-5 window, so alternate the early start: one week CAT takes the early slot, the next week MST does.
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.
About MST (Mountain Standard Time)
Mountain Standard Time (MST) covers the Rocky Mountain region of the United States and Canada. Arizona is notable for not observing daylight saving time, staying on MST year-round (except the Navajo Nation). The time zone includes major cities like Denver, Phoenix, Calgary, and Salt Lake City. During summer, most areas switch to Mountain Daylight Time (MDT, UTC-06:00).
Best time to call between CAT and MST
With a -9h offset there is no overlap inside a normal 9 AM – 5 PM day. MST opens at 9:00 AM MST, which is 12:00 AM in CAT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
CAT and MST have no shared working hours because of the -9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
CAT is 9 hours behind MST (CAT UTC+02:00 → MST UTC-07:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
