The annual festival, also known as “Rakhi”, always falls on a full moon and symbolizes a sister’s love for her brother, and brother’s life-long vow to protect his sister.

On the day of the Raksha Bandhan, a sister ties a decorative thread called “rakhi” on the wrists of her brother. In return, he gives her money, sweets, and other gifts.
