What is Zero Shadow Day?
‘Zero Shadow Day’ is a phenomenon that occurs when the sun is directly overhead, resulting in no shadows being cast by objects at noon. This typically happens in regions near the equator, where the sun’s angle is almost perpendicular to the Earth’s surface. As the Earth orbits the sun, changing its position in the sky, the sun reaches its zenith at different latitudes at different times of the year. This movement creates the seasons and causes the sun to shift from 23.5 degrees south of the equator to 23.5 degrees north, and back again, annually.

According to the Astronomical Society of India, ‘Zero Shadow Day’ occurs twice a year in locations between the latitudes of +23.5 and -23.5 degrees. The phenomenon takes place when the Sun’s declination matches the latitude of the location. Although the alignment lasts only momentarily, its impact can be observed for up to two minutes.

The Indian Institute of Astrophysics (IIA) in Bengaluru will host events on April 24 to mark ‘Zero Shadow Day’ at its Koramangala campus. The public is invited to join the activities from 10 AM to 1 PM, where participants can observe and measure changing shadow lengths of objects and gain insights into the Earth’s tilt and orbit around the sun.
Last year, Bengaluru experienced ‘Zero Shadow Days’ on April 25 and August 18.
