Why people convert CAT to GST time
- Scheduling a call from CAT to GST: a 10:00 AM start in CAT lands at 12:00 PM in GST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both CAT and GST are inside the 9-to-5 working day between 9:00 AM and 3:00 PM CAT time (11:00 AM–5:00 PM GST). That is roughly 6 hours of usable overlap.
- Coordinating a CAT-based team with GST 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 CAT" is unambiguous; "3 PM" across a +2h gap is not.
- Block 9:00 AM–3:00 PM CAT as the recurring meeting window if you work primarily from CAT and need GST 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.
About GST (Gulf Standard Time)
Gulf Standard Time (GST) is the time zone used in the United Arab Emirates, Oman, and other Gulf states. GST does not observe daylight saving time. Dubai and Abu Dhabi, major international business and tourism hubs, operate on GST.
