Daylight in Waipahu right now
Waipahu sits at 21.38° north, so its day length swings by 2h 36m across the year — from 10h 49m at the December solstice to 13h 26m at the June solstice. Today the city gets 12h 07m of daylight and the day is 1m 14s shorter than yesterday.
Day and night reach almost exactly twelve hours each on Monday, September 28, 2026 — the next equilux. That is not the equinox, and the gap is not an error: sunrise and sunset are measured at the sun’s upper edge rather than its centre, and atmospheric refraction lifts the disc into view before it has geometrically risen. The further from the equator, the larger the gap.
Solar noon — when the sun is highest, not when the clock reads twelve — comes at 12:24 PM. The difference is the combined effect of the city’s longitude within its time zone and the equation of time, which is currently 7.4 minutes.
