Bengaluru to observe 'Zero Shadow Day' today: Check time and other details

India's technological hub, Bengaluru is all set to experience a unique celestial event on Tuesday, 25 April. As stated by the Astronomical Society of India (ASI), any vertical objects in the city will not have any shadows during the phenomenon which is said to be 'Zero Shadow Day'.

It is expected to take place approximately at 12:17 PM and will remain in place for a brief period. Speaking of which, the phenomenon will be the result of the sun's position which will be directly overhead, thus leaving no place to cast a shadow. While arrangements have been made at the Indian Institute of Astrophysics (IIA) in Bengaluru's Koramangala to mark the event, citizens across the city are also prepared to witness the event.

Zero Shadow Day-related posts are already up on Twitter as people are excited to experience the unique and rare phenomenon this afternoon.

About Zero Shadow Day

The unique and rare phenomenon that usually happens at different times for different places on Earth is a brief period when the sun is exactly overhead at noon without any alignment. On normal days, the sun's position is not exactly overhead, but a little bit aligned to the North or to the South. On Zero Shadow Day, "the Sun's declination will be equal to the latitude twice - once during Uttarayan and once during Dakshinayan. On these two days, the Sun will be exactly overhead at noon and will not cast a shadow of an object on the ground," as stated by the Astronomical Society of India (ASI).
