I mean the entire Navratri is dedicated to her, it is one of the most celebrated festivals, Durga Puja is her festival. In fact, we don't have just one Sharadiya Navratri alone.. We have Gupt Navratri, Chaitra Navratri etc.
In all of them she is worshipped by devotees. Be it as Nav Durga or Dasha Mahavidyas. Also, this entire creation itself is her festival.
Jai Bhavani 🙏
