Residents of Bengaluru are preparing to witness a unique astronomical event known as 'Zero Shadow Day' on Wednesday.
During 'Zero Shadow Day,' shadows will briefly disappear between 12:17 pm and 12:23 pm on April 24 in Bengaluru, due to the Sun being directly overhead.
Bengaluru experiences Zero Shadow Day twice a year, typically around April 24/25 and August 18, coinciding with the equinoxes in March and September.
In addition to Bengaluru, other cities such as Kanyakumari, Bhopal, Hyderabad, and Mumbai are also expected to witness the phenomenon.
Various cities across India experience Zero Shadow Day on different dates, depending on their latitude. For instance, Kanyakumari observes it on April 10 and September 1, while Hyderabad experiences it on May 9 and August 5.
Zero Shadow Day occurs due to Earth's axial tilt of about 23.5 degrees and its orbit around the Sun. It is most pronounced in equatorial regions.
This event holds cultural and educational significance, providing an opportunity to educate people about Earth's axial tilt and its effects on sunlight angles.
Zero Shadow Day occurs biannually in regions between the Tropic of Cancer and the Tropic of Capricorn, with dates varying based on specific locations and latitudes.
As a unique astronomical occurrence, Zero Shadow Day is celebrated as an opportunity to increase public awareness about Earth's orbit and the changing angles of sunlight throughout the year.
