Today's Hours by Planet in Nairobi
Planetary Hours in Nairobi Through 2026
Nairobi is close enough to the equator that its daytime and nighttime hours stay within 2 minutes of each other all year; a daytime hour never drops below 60 minutes or passes 61.
Because Nairobi lies between the tropics, the noon Sun passes straight overhead twice a year, on Mar 17 and Sep 26.
Nairobi lies west of the meridian its clocks follow (UTC+3), so the Sun, and with it the first planetary hour, runs about 33 minutes behind the clock: noon by the Sun comes near 12:33 PM standard time.
