Chandra Grahan is a term used in India to refer to a lunar eclipse. It is a celestial event that occurs when the Earth passes between the Sun and the Moon, casting a shadow on the Moon and causing it to appear reddish-brown in color. The term "Chandra Grahan" is derived from Sanskrit, with "Chandra" meaning Moon and "Grahan" meaning to seize or grasp. The event is considered significant in Indian culture and is often associated with spiritual and mystical significance. The most recent Chandra Grahan occurred on October 28, 2023, and was a partial lunar eclipse visible from many parts of the world.
