Today's Hours by Planet in Singapore
Planetary Hours in Singapore Through 2026
Singapore 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 Singapore lies between the tropics, the noon Sun passes straight overhead twice a year, on Mar 24 and Sep 20.
Singapore lies west of the meridian its clocks follow (UTC+8), so the Sun, and with it the first planetary hour, runs about 65 minutes behind the clock: noon by the Sun comes near 1:05 PM standard time.
