Question

Quizplus · Accepted Answer

A sidereal day is approximately 4 minutes shorter than a solar day, which our current calendar is based on. This means that if we used a sidereal day for our calendar, the time of solar noon (when the Sun is highest in the sky) would shift earlier by about 4 minutes each day compared to our clocks. Over time, this discrepancy would accumulate, causing significant shifts in the timing of day and night relative to our standard clock time.
