Raksha Bandhan (the bond of protection in Hindi, Punjabi, Oriya, Assamese and most other Indian languages) is a Hindu festival, which celebrates the relationship between brothers and sisters. It is celebrated on the full moon of the month of Shraavana (Shravan Poornima).
The festival is marked by the tying of a rakhi, or holy thread by the sister on the wrist of her brother. The brother in return offers a gift to his sister and vows to look after her while presents sweets to her brother. The brother and sister traditionally feed each other sweets.
