Honoring Bahá'u'lláh's appointment of ‘Abdu'l-Bahá; work goes on. The Day of the Covenant is a holy day in the Baháʼí Faith that commemorates the appointment of ʻAbdu'l-Bahá as the Centre of Baha'u'llah's Covenant. It occurs annually on November 25 or 26. Since May 23 was the day that the Báb declared his mission, ʻAbdu'l-Bahá stated that it should be exclusively associated with the Báb and under no circumstances be celebrated as his birthday. However, the Baháʼís requested a day to celebrate and honor ʻAbdu'l-Bahá, and he designated November 26, 181 days after the ascension of Baháʼu'lláh, to be observed as the day of the appointment of the Centre of the Covenant. The observance was originally known as the Jashn-i-Aʻzam in Persian ("The Greatest Festival"), reflecting ʻAbdu'l-Bahá's title as "the Greatest Branch"; in the West, the holy day became known as the Day of the Covenant.
