Navaratri is an annual Hindu festival observed in honor of the goddess Durga, an aspect of Adi Parashakti, the supreme goddess. It spans over nine nights, first in the month of Chaitra, and again in the month of Ashvin (September–October). It is observed for different reasons and celebrated differently in various parts of the Hindu Indian cultural sphere. Theoretically, there are four seasonal Navaratri. However, in practice, it is the post-monsoon autumn festival called Sharada Navaratri. There are 2 Gupta Navaratris or "Secret Navaratris" as well, one starting on the Shukla Paksha Pratipada of the Magha Month and another starting in the Shukla Paksha Pratipada of Jyestha Month.
