Daylight in Rolla right now
Rolla sits at 37.95° north, so its day length swings by 5h 16m across the year — from 9h 31m at the December solstice to 14h 47m at the June solstice. Today the city gets 12h 09m of daylight and the day is 2m 25s shorter than yesterday.
Day and night reach almost exactly twelve hours each on Saturday, September 26, 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 12:59 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.
