Why people convert Oslo to CAT time
- Scheduling a call from Oslo to CAT: a 10:00 AM start in Oslo lands at 10:00 AM in CAT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Oslo and CAT are inside the 9-to-5 working day between 9:00 AM and 5:00 PM CEST time (9:00 AM–5:00 PM CAT). That is roughly 8 hours of usable overlap.
- Watching a live event or market open: Oslo viewers need 9:00 AM in CAT to catch a 9:00 AM start there, and 12:00 AM if the event is anchored to Oslo.
- Always state the zone abbreviation, not just the hour. "3:00 PM CEST" is unambiguous; "3 PM" across a +0h gap is not.
- Block 9:00 AM–5:00 PM CEST as the recurring meeting window if you work primarily from Oslo and need CAT colleagues present.
- Oslo: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +0h gap.
About CET (Central European 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.
