Bhau-beej
Bhai Dooj(भाई दूज) / Bhau-Beej / Bhai Tika / Bhai Phonta(ভাইফোঁটা) is a festival celebrated by Hindus of India and Nepal on the last day of the five-day-long Diwali or Tihar festival. This is the second day of the bright fortnight or Shukla Paksha of the Hindu lunar month of Kartika in Bikram Sambat.
The celebrations of this day are similar to the festival of Raksha Bandhan. On this day, sisters pray for a long and happy life for their brothers, by performing the Tika ceremony.
