Riḍván is a twelve-day festival in the Bahá'í Faith, running from sunset on April, 20 until sunset on May, 2nd. The festival commemorates the commencement of Bahá'u'lláh's prophethood. Ridván means paradise, and is named for the Garden of Ridván, outside Baghdad where Bahá'u'lláh stayed for twelve days after the Ottoman Empire exiled him from Baghdad and before commencing his journey to Constantinople.
It is the most holy Bahá'í festival, and is also referred to as the "Most Great Festival" and the "King of Festivals".
