The Bahá’í Calendar
Every new religion has brought its own calendar, and the Bahá’í Faith is no exception. The Bahá’í calendar begins on 21 March, the vernal equinox, and divides the year into 19 months of 19 days each. There are nine holy days in the Bahá’í year on which Bahá’ís suspend work to commemorate various events in the Faith’s history, such as the birth of Bahá’u’lláh and the martyrdom of the Báb. The announcement of Bahá’u’lláh’s Revelation is celebrated during a twelve-day festival known as Ridvan, at the end of April and beginning of May. With the division of the year into 19 months, four intercalary days are needed. These days occur at the end of February and are celebrated as a gift-giving time known as Ayyám-i-Há.
