Bhai Dooj, the final day of the 5-day Diwali festivities, celebrates the bond between brothers and sisters.
On this day, also known as Yama Dwitiya, sisters pray for their brothers’ well-being and brothers give gifts to their sisters, marking the festival’s loving conclusion.
Bhai Dooj falls on the Dwitiya (2nd) Tithi of the Shukla Paksha (bright fortnight) in the Hindu month of Kartik. For 2025, the tithi begins on 22 October at 8:16 PM and ends on 23 October at 10:46 PM.
The most auspicious window for the tilak ceremony, when sisters apply tilak to their brothers, is during the Aparahna (afternoon) period, which falls between 1:13 PM and 3:28 PM on 23 October.
Bhai Dooj celebrates the bond between brothers and sisters: the sister’s care for the brother and the brother’s promise of protection.
The tilak ritual symbolises the sister’s prayers for her brother’s long life, and his blessings/gifts in return.
Yamuna welcomed Yama, applied a tilak, did aarti, and served him sweets. Moved by her devotion, Yama granted that any brother who receives his sister’s tilak on this day will not be afraid of death and will enjoy a long life.
Hence, the day is also called Yama Dwitiya.
After Lord Krishna’s victory over the demon Narakasura, his sister Subhadra welcomed him with a tilak and sweets; this event is linked to the origin of the tilak ritual in Bhai Dooj.
