The 'Year Nine' is an abbreviation of 1269 A.H. The
beginning of the Year Nine occurred about two months after His (Bahá'u'lláh's)
imprisonment in that dungeon. [August-December] We do not know the exact time
He received this first intimation... We therefore regard the entire Year Nine
as a Holy Year, and the emphasis should be placed ... on the entire year, which
started in October, 1852...
