Karva Chouth Calander - The Legend Of Karva According to another legend, a woman named Karva was deeply devoted to her husband. One day while bathing, her husband was caught by a crocodile. Karva came running and tied the crocodile with a cotton yarn. She then went to Yamraj and appealed him to send the offending crocodile to hell. When Yamraj refused, Karva threatened to curse him. Afraid of the power of a devoted wife, Yamraj readily accepted and sent the crocodile to hell, and blessed Karva's husband with long life.
