The Ascension of Abdu’l-Bahá is a Baha’i holy day that commemorates the death of Abdu’l-Bahá, the son and successor of the founder of the Baha’i Faith, Baháʼu'lláh. It is observed on November 27 or 28 each year and marks the passing of `Abdu’l-Bahá, who led the Baha’i community from 1892 until his death on November 28, 1921. Baha’is commemorate this day with devotional readings, particularly at 1:00 a.m., the time he passed away.
