I know there are lot of festivals/events which are very specifically celebrated in a State/town. If you guys can share those information, it would benefit for those who are really interested to take part in it (I am very much interested in such events ). Natyanjali is one grand classical dance festival which happens during Shivratri at the temples of Chidambaram, Mayavaram, Kumbakonam and Tanjore. I have heard of Pushkar (Camel festival) in Rajasthan. Thirupunithura temple festival in Kerala. Now, I leave it to you guys to share these information.
