Presiding deity: Rudra (Shiva)
Ashtami is the eighth lunar day, ruled by Rudra (the fierce form of Shiva). Generally considered inauspicious for new worldly ventures. Krishna Ashtami of Bhadrapada is Krishna Janmashtami — one of the most significant worship days. During Navratri, Maha Ashtami is a powerful day for Devi worship.
