To mark this wonderful sibling's bond, Raksha Bandhan is celebrated every year in India. According to the Hindu calendar, Raksha Bandhan or Rakhi, is celebrated on the last day of the month of Shravana. During this occasion, sisters tie beautifully decorated bands, also known as rakhis, on their brother's wrist. While sisters pray for their brother's good health, in return brothers promise to protect their sister's and stand by them through every thick and thin.
