What is a day without darkness?
A Shadowless Day, also known as a Shadowless Day, is an astronomical phenomenon that occurs in specific regions of the Earth where the Sun is directly overhead at noon. This phenomenon occurs because the Earth’s axis is tilted about 23.5 degrees and its orbit around the Sun.
Between Tropic of Cancer (about 23.5 degrees north of the equator) and Tropic of Capricorn (about 23.5 degrees south of the equator), there are instances where the Sun is exactly overhead at noon. local sun. This means that vertical objects, such as poles or sticks, cast little or no shadow when the Sun’s rays fall almost vertically.
When does Zero Shadow Day happen?
According to the Astronomical Society of India (ASI), Shadowless Days typically occur twice a year in these tropics, around the time the Sun crosses the zenith. These dates may vary depending on the specific location and its latitude. The phenomenon has cultural and educational significance and is often celebrated as a unique astronomical event. It provides an opportunity to teach people about the tilt of the Earth’s axis, its orbit around the Sun, and the changing angles of sunlight throughout the year.
