Why people convert CAT to Denver time
- Scheduling a call from CAT to Denver: a 10:00 AM start in CAT lands at 2:00 AM in Denver, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: CAT and Denver 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 Denver is 1:00 AM in CAT.
- Watching a live event or market open: CAT viewers need 1:00 AM in Denver to catch a 9:00 AM start there, and 8:00 AM if the event is anchored to CAT.
- Always state the zone abbreviation, not just the hour. "3:00 PM CAT" 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 CAT takes the early slot, the next week Denver does.

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.

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).
