People in Bengaluru too experienced ¡®Zero Shadow Day¡¯ at 12:18 pm where the sun was at its zenith and there was almost no visible shadow.
At Tamil Nadu Science and Technology Centre (TNSTC), a group of 60 students studied the longest and shortest shadow time.
So what exactly is the Zero Shadow Day?

The sun is exactly overhead and casts almost no shadow because the sun rays hit the surface perpendicularly and your shadow comes to rest right beneath you. This makes it seem like there's no shadow.

People who live between the latitudes 23.5 degrees south (the tropic of Capricorn) and 23.5 degrees north (the tropic of Cancer) can experience the sun right overhead at zenith.
Bengaluru experiences two Zero Shadow days in a year, with the next one set to come on August 18.
