Thiruvathira is a significant festival in Kerala, India, primarily celebrated by Hindus. It occurs in the Malayalam month of Dhanu (December-January) on the day of the Thiruvathira Nakshatra (star). The festival holds cultural and spiritual significance and is especially popular among women. Here's an overview:
1. Mythological Significance

    Lord Shiva and Parvati: Thiruvathira is believed to commemorate the cosmic dance (Tandava) of Lord Shiva and the union of Lord Shiva with Goddess Parvati.
    Marking Lord Shiva's Birth: Some traditions associate the day with the birth of Lord Shiva.
    Kamadeva's Sacrifice: It is also linked to the story of Kamadeva (God of Love), who was burned to ashes by Lord Shiva’s third eye but later restored to life.

2. Cultural Practices
