How long is a tidal day?

Explanation:
A tidal day is defined as the time it takes for the Earth to rotate on its axis with respect to the Moon. It is longer than a solar day, which is the typical 24-hour period we reference for day-to-day timekeeping. A tidal day is approximately 24 hours and 50 minutes. This additional time accounts for the position of the Moon as the Earth rotates, resulting in the need for an extra 50 minutes in a complete cycle of high tides and low tides. Understanding the length of a tidal day is important for navigation and operations at sea, as it directly influences tidal patterns and helps mariners predict tidal movements and conditions in various locations.
