Why is navratri celebrated for 9 days?

Navratri is celebrated for 9 days because it represents the nine nights when Goddess Durga battled the demon Mahishasura and ultimately defeated him on the tenth day (Vijayadashami).

Symbolic significance of the 9 days: - Each day is dedicated to a different form of Goddess Durga - The battle lasted 9 nights and 10 days - It represents the victory of good over evil - The number 9 is considered auspicious in Hindu tradition

The nine forms worshipped: 1. Shailaputri 2. Brahmacharini 3. Chandraghanta 4. Kushmanda 5. Skandamata 6. Katyayani 7. Kalaratri 8. Mahagauri 9. Siddhidatri

The celebration also coincides with the change of seasons (spring and autumn), making it a period of spiritual cleansing and renewal. Different regions of India celebrate Navratri with varying traditions, but the 9-day structure remains consistent across the country.

The tenth day (Dussehra or Vijayadashami) celebrates the final victory, which is why the festival essentially spans 9 nights and 10 days in total.
