SUMMARY
The Earth's rotation period is approximately 23 hours and 56 minutes, leading to a discrepancy with the 24-hour day used in clocks. This difference arises from the need to align timekeeping with the Sun, which is essential for biological rhythms. As the Earth orbits the Sun, it must rotate an additional degree each day to maintain its position relative to the Sun, resulting in a solar day that is about four minutes longer than a sidereal day. This phenomenon is crucial for understanding timekeeping and its relationship with celestial movements.
