The last day of the Festival of Ridván (Baháʼí Faith) (this date is non-Gregorian and may change according to the March equinox, see List of observances set by the Baháʼí calendar)
Ridván
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 2025, it begins in the evening of 20 April. On the first, ninth and twelfth days of Ridván, work and school should be suspended.
Baháʼí Faith
The Baháʼí Faith is a religion founded in the 19th century that teaches the essential worth of all religions and the unity of all people. Established by Baháʼu'lláh, it initially developed in Iran and parts of the Middle East, where it has faced ongoing persecution since its inception. The religion has 5–8 million adherents spread throughout most of the world's countries and territories.
March equinox
The March equinox or northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. The March equinox is known as the vernal equinox in the Northern Hemisphere and as the autumnal equinox in the Southern Hemisphere.
