How much do you know about the Baháʼí festival of Riḍván?

Study Notes

Riḍván is a twelve-day festival in the Baháʼí Faith.
It commemorates Baháʼu'lláh's declaration that he was a Manifestation of God.
The festival begins at sunset on the 13th of Jalál, which translates to the 20th or 21st of April.
Work and school should be suspended on the first, ninth and twelfth days of the festival.
"Ridván" means paradise and is named after the Garden of Ridván outside Baghdad.
It is the holiest Baháʼí festival and is also referred to as the "Most Great Festival" and the "King of Festivals".
Baháʼu'lláh's rising prominence in the city of Baghdad gained the attention of his enemies in Islamic clergy and the Persian government.
Baháʼu'lláh's declaration took place in the Najibiyyih garden across the Tigris river from Baghdad.
The festival is observed according to the Baháʼí calendar and begins on the thirty-second day of the Baháʼí year.
The festival is significant because of Baháʼu'lláh's private declaration to a few followers that he was "Him Whom God shall make manifest" and a Manifestation of God, and thus it forms the beginning point of the Baháʼí Faith, as distinct from the Babi religion.
