Bhai Dooj Festival is celebrated in the month of October or November. The date is not fixed and is calculated every year by the Pandits. It falls on the new moon night, approximately one day after the festival of Diwali. The name Bhai Dooj, with "bhai" meaning brother and "dooj" meaning the second day after the new moon (the day of the festival), literally means the day of the brother. Bhai Dooj is also known as the festival of Tikka. The festival of Bhaiya Duj signifies the bond of love between a brother and a sister. The sister applies tilak (saffron and vermilion) on the forehead of her brother, performs aarti and offers sweets. In return, the brother blesses her and gives her nice presents. These presents form a part of Tikka celebrations in New Delhi, India also.
There are a number of legends associated with the festival of Bhai
Dooj. One of the legends has it that Yamraj, the God of death, visited
his sister Yamuna on the day of Bhaiya Duj. She adorned his forehead
with the auspicious tilak (saffron and vermilion), garlanded him and fed
him with special dishes and sweets. At the time of leaving, Yamraj gave
her a special gift as a token of his adoration and in return she also
gifted him a present that was made by her. On that day Yamraj announced
that anyone who receives tilak from his sister would never be thrown
into hell. From that day onwards, Bhaiya Dooj is celebrated and is also
known by the name of "Yama Dwitiya".
Another legend goes that Lord Krishna went to his sister, Subhadra's
house, after annihilating Narakasura demon. She welcomed him with arti
(lamp), flowers and sweets. Thereafter, she put the Tikka, holy
protective tilak, on his forehead. From that day onwards, the festival
of Tikka is celebrated as a mark of affection between brothers and
sisters. Following these legends, it has become the tradition that it is
the brother who goes to his sister's house to celebrate Bhai Dooj and
not the other way around.
