It’s a rare celestial phenomenon that happens twice a year in locations situated between +23.5 and -23.5 degrees latitude. During this event, shadows of all objects and living beings disappear when the sun reaches its highest point in the sky. According to the Astronomical Society of India (ASI), when the sun is directly at the zenith position, it doesn’t cast a shadow on any object. “For people living between +23.5 and -23.5 degrees latitude, the Sun’s declination will be equal to their latitude twice – once during Uttarayan and once during Dakshinayan. On these two days, the Sun will be exactly overhead at noon and will not cast a shadow of an object on the ground,” explains the ASI on its website.
