Shardiya Navratri is the most popular and significant Navratri of all Navratris. That's why Shardiya Navratri is also known as Maha Navratri.
It falls in lunar month Ashwin during Sharad Ritu. The name Shardiya Navratri has been taken from Sharad Ritu. All nine days during Navratri are dedicated to nine forms of Goddess Shakti. Shardiya Navratri falls in the month of September or October. The nine days festivity culminates on tenth day with Dussehra or Vijaya Dashami.
Women, especially in Maharashtra and Gujarat, adorn themselves with 9 different colors which are allocated to each day of Navratri. The color of the day is decided on the weekday. Each weekday is ruled by one the planets or Navgrahas and accordingly colors are assigned to each day.
