Festivals of the Twin Birthdays – Birth of the Bab
November 6 @ 12:00 am - 11:59 pm
The Festivals of the Twin Birthdays or the Twin Holy Birthdays refers to two successive holy days in the Baháʼí calendar that celebrate the births of two central figures of the Baháʼí Faith. The two holy days are the birth of the Báb on the first day of Muharram in the Islamic calendar (20 October 1819) and the birth of Baháʼu’lláh on the second day of Muharram (two years prior, on 12 November 1817).
They are observed on the first and the second day following the occurrence of the eighth new moon after Naw-Rúz, as determined in advance by astronomical tables using Tehran as the point of reference. This results in the observance of the Twin Birthdays moving, year to year, within the months of Mashíyyat, ʻIlm, and Qudrat of the Baháʼí calendar, or from mid-October to mid-November in the Gregorian calendar.
The notion of “twin Manifestations of God” is a concept fundamental to Baháʼí belief, describing the relationship between the Báb and Baháʼu’lláh. Both are considered Manifestations of God in their own right, having each founded separate religions (Bábism and the Baháʼí Faith) and revealed their own holy scriptures. To Baháʼís, however, the missions of the Báb and Baháʼu’lláh are inextricably linked: The Báb’s mission was to prepare the way for the coming of Him whom God shall make manifest, who eventually appeared in the person of Baháʼu’lláh. For this reason, both the Báb and Baháʼu’lláh are revered as central figures of the Baháʼí Faith. A parallel is made between Baháʼu’lláh and the Báb as between Jesus and John the Baptist.
In the Kitáb-i-Aqdas, Baháʼu’lláh wrote that his birthday and that of the Báb “are accounted as one in the sight of God”.
