Q. Recently, Zero Shadow Day was observed in which region of India?
Answer: Pondicherry
Notes: Zero Shadow Day was recently observed in Pondicherry. It happens twice yearly between the Tropic of Cancer and the Tropic of Capricorn, occurring between the December and June solstices, and vice versa. This phenomenon is exclusive to latitudes within +23.5 and -23.5 degrees. On this day, the Sun is directly overhead, casting no shadows. This occurs when sunlight strikes surfaces perpendicularly, resulting in shadows being obscured.
