The Festival of Ridván, the “King of Festivals” is celebrated by the Bahá’ís from April 21 to May 2. It was during those twelve days in 1863 that Bahá’u’lláh received visitors in the Najibiyyih Garden outside Baghdad, and made the stupendous announcement to at least four of His closest followers that He was in fact the Promised One prophesied and awaited by all the major religious traditions and scriptures.
Furthermore, three of these days have been designated as Holy Days. The first and last are understood easily enough, but what about the ninth? We read so often that His family visited Him on the Ninth Day that we can get the idea that it is because of their arrival that that particular day is celebrated. Except for Naw-Rúz (New Year, March 21), the Bahá’í Holy Days are all associated with the Twin Manifestations, the Báb and Bahá’u’lláh. We do not know who these family members were or how many (they did not include ‘Abdu’l-Bahá, who was there from the First Day); for all we know they may have been future Covenant-breakers, and it would be inconceivable to have a Holy Day associated with covenant-breaking. And it was likely that their arrival would have been earlier had it not been for high rushing waters of the Tigris River (The Najibiyyih Garden was on an island) imperiling any crossing.
We have a direct if rather prosaic explanation from the writings themselves:
“. . . the reason we commemorate the 1st, 9th and 12th days of Ridván as Holidays (Holy Days) is because one is the first day, one is the last day, and the third one is the ninth day, which of course is associated with the number 9. All 12 days could not be holidays, therefore these three were chosen.”

A note of caution regarding the above photograph of the Ridván Garden. This, and every other photo is of the one outside ‘Akká in the Holy Land, and was called that name by Bahá’u’lláh Himself. It is NOT the one associated with the “King of Festivals.” The Ridván Garden outside of Baghdad is at present a hospital parking lot. May the All-Powerful Lord restore it to the condition in which roses could be piled so high in Bahá’u’lláh’s tent that one could not see over them.
