fasts and vrats
What is the Bhai Dooj (Yama Dwitiya) vrat and is there a fasting tradition associated with it?
The festival and its story
Bhai Dooj falls on Kartik Shukla Dwitiya, the second day of the bright half of the month of Kartik, which comes two days after Diwali. The festival is also called Yama Dwitiya. According to the tradition, on this day the god Yama, who rules death, visited his sister Yamuna. She welcomed him with love and marked his forehead with tilak, a mark of blessing and protection. She prayed for his long life and well-being. In return, Yama blessed her and promised that anyone who celebrates this bond between brother and sister on this day will be protected from harm. This story, found in the Skanda Purana, is the heart of the festival.
The fasting practice
Sisters observe a vrat, or fast, on Bhai Dooj. The fast is kept from morning until the tilak ceremony is completed. The sister fasts and prays for her brother's long life, health, and happiness. After the ritual—in which she applies tilak to her brother's forehead and sometimes feeds him sweets or a meal—the fast is broken. The brother also eats at his sister's home as part of the celebration. In some families, the brother gives a gift to his sister, and in others, the sister gives gifts to the brother. The exact customs vary by region and family.
Why this day matters
Bhai Dooj celebrates the bond between brother and sister. The sister's fast and prayer are seen as an act of love and protection. The tilak she applies is a blessing, a mark that says she wishes him safety and a long life. The festival mirrors Raksha Bandhan, another celebration of sibling bonds, but here the sister takes the lead in the ritual. For many, it is a day to honor and strengthen family ties, especially across distance. In the diaspora, siblings often celebrate it even when they live far apart, sometimes over a video call or by sending tilak and sweets.
Today
The festival is widely observed in North India and among Hindu families worldwide. Some sisters keep a full fast, while others eat fruit or light food during the day. Some brothers travel home for the day; others celebrate with their sisters wherever they are. The fasting part is not strict in all families—some see the ritual and the prayer as the main thing. The festival remains a cherished way to mark sibling love and to wish each other well.
