Navratri is a Hindu festival that is celebrated over nine nights and ten days, typically falling between September and October during the month of Ashvin. The word "Navratri" means "nine nights" in Sanskrit, and it is observed for different reasons and celebrated differently in various parts of the Hindu Indian cultural sphere. Here are some key points about Navratri:

• Goddess Durga: Navratri is observed in honor of the goddess Durga, an aspect of Adi Parashakti, the supreme goddess. Durga is best known for killing an evil demon in a battle which lasted nine days and nights, and that is why the festival lasts for nine days and nights as well.

• Victory of Good over Evil: The festival ends with whats known as Dussehra, which is the celebration of good over evil. It is believed that Rama, the seventh avatar of Vishnu, was advised to worship the Goddess to ensure victory over his enemy Ravana.

• Different Forms of Devi: During Navratri, various forms of the Devi are worshipped. Each day of Navratri has an associated color which devotees are encouraged to wear.

• Fasting: During Navratri, some families choose to fast, only having milk, water, fruit, and nuts during the day, followed by a full meal after sunset.

• Different Celebrations: Navratri is celebrated differently in Indias various regions. For many people, it is a time of religious reflection and fasting, while for others, it is a time of prayer and rejuvenation.

Navratri is a significant time for devotees to fast, meditate, and pray to the Divine Mother for inner strength and skills to combat their own demons (or problems) of life.
