‘Ridvan’ means paradise and the 12-day festival is the holiest time for the Bahá’ís. It commemorates the 12 days that Baha’u’llah spent in the Garden of Ridvan in the last days of his exile in Bagh dad and announced that he was the prophet whose coming had been foretold. The Bahá’ís do not work on the first, ninth and twelfth day of Ridvan.
