Why people convert Nairobi to CAT time
- Scheduling a call from Nairobi to CAT: a 10:00 AM start in Nairobi lands at 9:00 AM in CAT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Nairobi and CAT are inside the 9-to-5 working day between 10:00 AM and 5:00 PM EAT time (9:00 AM–4:00 PM CAT). That is roughly 7 hours of usable overlap.
- Coordinating a Nairobi-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 EAT" is unambiguous; "3 PM" across a -1h gap is not.
- Block 10:00 AM–5:00 PM EAT as the recurring meeting window if you work primarily from Nairobi and need CAT colleagues present.

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.
