- Chennai observed Zero Shadow Day on 25-04-19.
- On this day the sun will be exactly overhead.
- It will cast almost no shadow of objects on the ground.
- This happens two times a year.
- This is because the sun rays will hit the surface perpendicularly on the object.
- Therefore, the shadow of the object will be directly beneath it.
- It occurs at different times in different places around the world
- In India, it is usually observed in April and September.
- It occurs only at places located between Tropic of Cancer and Tropic of Capricorn.
- Therefore, Indian places like Delhi, Allahabad, Srinagar, located away from the Tropic of Cancer have no zero-shadow day.
