Kartika Purnima is a significant Hindu festival celebrated on the full moon day of the month of Kartika, which usually falls in November. It marks the end of the Kartika month and is dedicated to various deities, particularly Lord Shiva and Lord Vishnu. Devotees often take holy dips in rivers, perform rituals, and light lamps to seek blessings. The festival is also associated with the Kartik Snan, where people bathe in sacred rivers to purify themselves. In some regions, it is celebrated as Dev Diwali, honoring the return of Lord Rama to Ayodhya after defeating Ravana. Various cultural events and fairs are organized, making it a vibrant occasion.
