Festival of the Twin Birthdays – Birth of Baha’u’llah

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”.


Born and raised in the capital city of Persia, Tehran, Baha’u’llah grew up as the son of a government minister and nobleman. But rather than pursuing his father’s career, early in his adulthood Baha’u’llah turned his attention to a life of service to the poor and needy. He sought no position or prominence, and as a young man accepted the religion of the Bab—which subjected Baha’u’llah and his family to terrible privation, persecution and imprisonment. Thirteen years after the government’s execution of the Bab in 1850, Baha’u’llah announced that he was the one foretold by the Bab—God’s messenger for humanity’s dawning golden age of unity and peace, promised in all the world’s scriptures:

A trusted messenger hath arrived and hath, in the world of the spirit, delivered a message from God’s loved ones. This auspicious courier bringeth fragrances of great ardour and wafteth the life-giving breezes of the love of God. He maketh the heart to dance for joy and filleth up the soul with an ecstasy of love and rapture. So intensely hath the glory of Divine Unity penetrated souls and hearts that all are now bound one to another with heavenly ties, and all are even as a single heart, a single soul. – Abdu’l-Baha, Selections from the Writings of Abdu’l-Baha, p. 19.

After his declaration in 1863, Baha’u’llah taught that no distinction of station exists between any of the prophets of God. He asked the Baha’is to view all of the messengers and prophets of God as one. So  Baha’u’llah’s message is intended not for select peoples or cultures, a single language or nation, but is meant for all peoples.

Baha’u’llah’s advent announced that the coming of age of the human species, the time when the human race might recognize itself as one, discover its fullness and its common humanity, has arrived. The Baha’i Twin Holy Days, then, signify the first universal celebration given to everyone by a loving Creator: “These two days are accounted as one in the sight of God.” –Baha’u’llahThe Most Holy Book, p. 105.
