1542. The Declaration of the Bab and the Birthday of Abdu'l-Bahá
"...regarding the declaration of the Bab and the birthday of the Master: The Bab declared His Mission on the fourth day of the month of Jamadi I, two hours and eleven minutes after sunset, corresponding with the evening of May 22nd. But as the Bahá'í day begins after sunset, and not after midnight as in the West, the Bab's declaration is celebrated on the fifth day of Jamadi I, corresponding to the 23rd of May. Abdu'l-Bahá was born in the course of that same night, but the exact hour of His birth has not been ascertained."
