Navratri is celebrated twice a year. One is in Chaitra month and the other is in Ashwin month of the Hindu calendar. One of the interesting facts about this festival is that each day of Navratri is dedicated to each incarnation of Goddess Durga. On Day 6, Goddess Katyayami is worshiped. She is a warrior goddess and she is considered one of the most powerful incarnations of Goddess Durga. If you want to please her and want to get success in your life, I would love to recommend you to read the write-up on the website of Dr. Vinay Bajrangi.
