Why people convert Seoul to CAT time
- Scheduling a call from Seoul to CAT: a 10:00 AM start in Seoul lands at 3:00 AM in CAT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Seoul and CAT are inside the 9-to-5 working day between 4:00 PM and 5:00 PM KST time (9:00 AM–10:00 AM CAT). That is roughly 1 hours of usable overlap.
- Watching a live event or market open: Seoul viewers need 2:00 AM in CAT to catch a 9:00 AM start there, and 7:00 AM if the event is anchored to Seoul.
- Always state the zone abbreviation, not just the hour. "3:00 PM KST" is unambiguous; "3 PM" across a -7h gap is not.
- Block 4:00 PM–5:00 PM KST as the recurring meeting window if you work primarily from Seoul and need CAT colleagues present.
About KST (Korea Standard Time)
Korea Standard Time (KST) is the time zone used in South Korea. It shares the same UTC offset as Japan Standard Time but is a distinct time zone. South Korea does not observe daylight saving time. Seoul, the capital, is a major global tech and business hub.
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.
