What Exactly Is Noon Time?
Noon time is defined as the moment when the sun is at its highest point in the sky for a given location. This moment is known as solar noon. Unlike civil noon, which is fixed at 12:00 PM in local time zones, solar noon can vary based on geographical location and the time of year. This variation occurs because the Earth's orbit around the sun is elliptical, and its axis is tilted.
At solar noon, the sun crosses the local meridian of the observer, which is an imaginary line that runs from the North Pole to the South Pole, passing directly overhead. This is the point of the highest solar elevation angle, meaning the sun appears at its highest position in the sky. This is why shadows are shortest at noon compared to other times of the day.
