Why is the suns movement referred to as solar noon and not regular noon?

Solar noon refers specifically to the time when the sun is at its highest point in the sky for a given location, resulting in the shortest shadow length. It is not necessarily the same as regular noon, which is often defined by a standard clock time (e.g., 12:00 PM) that may vary due to time zones and Daylight Saving Time. Therefore, while regular noon is a consistent time on the clock, solar noon is determined by the sun's position and can vary throughout the year and across different geographical locations.
