The fifth and last day of Diwali is known as 'Bhai duj' or 'Bhai Bij'. The name itself denotes the day of the festival i.e it falls on Dooj, the second day after the new moon. This day Yamaraj went to his sister's house who put an auspicious mark on his forehead for his welfare.

Another version is after killing Narakasur, Lord Krishna, on his "Dooj Day' went to his sister Subhadra who welcomed him in the traditional way by showing him a light and putting on his forehead a tilak of her sisterly protection.

Another myth behind this begins as when Bhagawaan Mahavir found nirvana, his brother Raja Nandivardhan was distressed because he missed him and was comforted by his sister Sudarshana. Since then, women have been revered during this festival.

This day all sisters show their sisterly love for their brother by giving them their traditional and loving welcome by applying tilak on the forehead of their brothers for their safety and well being. They are then given gifts from their brothers and held in the highest respect.
