Raksha Bandhan is a popular festival celebrated across the country. Irrespective of caste and creed people from all walks of life participate in this festival. It is celebrated on the full moon day of the lunar month Shravana (Shravana Poornima) which also coincides with Upa-karma (changing the sacred thread for the brahmins, Avani Avittom in South India).
The concept of Raksha Bandhan is mainly that of protection. Commonly we find people going to the priests in temples and getting a sacred thread tied to their hands.
