Daylight saving time note
London and Nairobi do not change their clocks on the same date. Between October 25, 2026 and March 28, 2027 the difference is 3 hours behind Nairobi — because London changes its clocks for daylight saving time while Nairobi keeps the same time all year.
For the rest of the year the difference holds steady at 2 hours. Every time on this page is computed from the IANA database at the moment you load it, so the tables above already account for whichever side has switched.
Why the time difference exists
The clock in London is anchored to UTC standard time; Nairobi works from UTC+3 standard time. Only London shifts for daylight saving; Nairobi stays put, which nudges the difference by an hour twice a year. Nairobi sits roughly 6,800 km to the southeast of London.
Expect roughly a 3 hours forward adjustment travelling from London to Nairobi. The direct distance works out to roughly 9 hours in the air. Line up a shared window before you call and the rest is easy.
