Twelve-day festival in the Baháʼí Faith
Riḍván is a twelve-day festival in the Bahá'í Faith commemorating Bahá'u'lláh's declaration that he was a Manifestation of God. In the Bahá'í calendar, it begins at sunset on the 13th of Jalál, which translates to the 20th or 21 April, depending on the date of the March equinox. In 2026, it begins in the evening of 21 April. On the first, ninth and twelfth days of Ridván, work and school should be suspended.
