Mumbai, April 24: Bengaluru is all set to witness a unique and rare celestial event tomorrow, April 25 called "Zero Shadow Day". In simple terms, people won't be able to see their own shadow or leave alone that of other people tomorrow. This unique phenomenon is called Zero Shadow Day. On Zero Shadow Day, the sun, which is the source of light comes exactly overhead at around noon time. Reportedly, all vertical objects in and across Bengaluru will not have a shadow of reflection for a short period of time.

Having said that, it's important to understand what Zero Shadow Day really is. As per the Astronomical Society of India (ASI), the rare phenomenon takes place when the Sun does not cast a shadow on an object at solar noon. This happens when the Sun is exactly at the zenith position, thereby causing the phenomenon to take place. Zero Shadow Day 2020 Dates and Timing: Know Why You Cannot See Your Shadow During This Amazing Phenomenon.
