Raksha Bandhan is a unspoken pledge exchange between a brother and a sister cementing their relationships. It is celebrated on the day of Shravan Purnima (full moon) that falls in the month of August every year. On this day, sister ties a delicate, sometimes decorative, thread on the wrist of their brothers and apply tilak on the forehead as a symbol of love and affection. The brother responds by giving a gift, implicitly pledging to protect his sister from danger. In some places in medieval India where women felt unsafe, they tied Rakhi around the wrists of men they could count upon. Later this practice changed and sister started typing Rakhi only on their brother's wrists. There are many legends that signify the importance of Rakhi in India.
