Karnataka's capital Bengaluru will witness 'Zero Shadow Day' celestial phenomenon at 12:17 pm today when the Sun will directly be overhead. 'Zero Shadow Day' occurs twice a year for locations between +23.5 and -23.5 degrees of latitude when the Sun doesn't cast a shadow of a vertical object at noon. In 2021, Odisha's Bhubaneswar had witnessed a 'Zero Shadow Day'.
