Mumbai witnesses Zero Shadow Day twice a year, once in May and once in July. This year, Mumbaikers were treated to the rare phenomenon on May 15 while the next Zero Shadow Day in the city is expected to be on July 28
Zero Shadow Day is a rare celestial phenomenon that occurs when the sun is directly overhead. Hence, vertical objects will cast no shadow
The Earth's axis is tilted at an angle of 23.5 degrees. This tilt causes the sun to appear to move higher or lower in the sky throughout the year. On Zero Shadow Day, the sun is directly overhead at the Tropic of Cancer. Zero Shadow Day is an important scientific event. It helps scientists to study the Earth's tilt and its impact on the seasons
