Chaitra Navratri, also known as Vasant Navratri, falls in the Hindu lunar month of Chaitra, typically in March or April according to the Gregorian calendar. It commemorates the arrival of spring and the rejuvenation of life on earth. During this time, devotees invoke the blessings of Goddess Durga and her nine divine forms, known as Navadurga, to seek strength, wisdom, and prosperity.
