Why people convert London to Nairobi time
- Scheduling a call from London to Nairobi: a 10:00 AM start in London lands at 12:00 PM in Nairobi, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both London and Nairobi are inside the 9-to-5 working day between 9:00 AM and 3:00 PM BST time (11:00 AM–5:00 PM EAT). That is roughly 6 hours of usable overlap.
- Coordinating a London-based team with Nairobi 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 BST" is unambiguous; "3 PM" across a +2h gap is not.
- Block 9:00 AM–3:00 PM BST as the recurring meeting window if you work primarily from London and need Nairobi colleagues present.
- London: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +2h gap.
