Bhadrotsav of Brahmo Samaj
Bhadrotsav is a religious festival observed by the Brahmos. The 6th of Bhadra 1234 B.E. (according to the Bengali calendar), or 20 August 1828, was the date when the doors of the first Brahmo Samaj were opened by Raja Rammohun Roy with his friend Tarachand Chakravarty as its first secretary. The Samaj initially functioned from a rented house belonging to Feranghee Kamal Bose and accommodated the first theistic congregation. To commemorate this historic event - Brahmos all over the world celebrate Bhadrotsav with divine service or prayers accompanied by devotional songs or Brahmasangeet.
It should also be noted that coincidentally or otherwise other Brahmo Samajees were also opened in this particular month of the year. On 22 August 1869 the consecration was held of the Brahmo Samaj of India or the Navavidhan Brahmo Samaj. The Brahmo Sammilan Samaj was also founded in August 1897.
The body of worshipers who used to assemble every week in the church consecrated by Rammohun were originally known as the Brahma Sabha and was later called the Calcutta Brahmo Samaj. It retained its name till 1866, the year of the first schism, after which it was changed to Adi or Original Brahmo Samaj to indicate its precedence in point of time to the younger branches.
