Why people convert AWST to CAT time
- Scheduling a call from AWST to CAT: a 10:00 AM start in AWST lands at 4:00 AM in CAT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both AWST and CAT are inside the 9-to-5 working day between 3:00 PM and 5:00 PM AWST time (9:00 AM–11:00 AM CAT). That is roughly 2 hours of usable overlap.
- Coordinating a AWST-based team with CAT 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 AWST" is unambiguous; "3 PM" across a -6h gap is not.
- Block 3:00 PM–5:00 PM AWST as the recurring meeting window if you work primarily from AWST and need CAT colleagues present.

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.
