Solar Noon at the Equator: When Does the Sun Directly Overhead Occur?

The sun shines directly overhead at the equator twice a year, during the spring and autumn equinoxes.

Here's why:

* Earth's Tilt: The Earth is tilted on its axis at approximately 23.5 degrees. This tilt is responsible for the seasons.

* Equinoxes: The equinoxes occur when the sun's rays are directly overhead at the equator. This happens twice a year:

* Vernal (Spring) Equinox: Around March 20th/21st.

* Autumnal (Fall) Equinox: Around September 22nd/23rd.

At these times, the Earth's axis is neither tilted towards nor away from the sun, resulting in equal day and night hours across the globe.
