Also known as Days of Ha, the Ayyam-i-Ha are intercalary days (extra days inserted in a calendar) in the Baha’i calendar. The calendar is made up of 19 months of 19 days, plus the period of four days added between the 18th and 19th months, which allows for the year to be adjusted to the solar cycle. The days are set aside for rejoicing, hospitality, gift-giving, special acts of charity, and spiritually preparing for the Baha’i fast from March 2-20. The new calendar was inaugurated by Mirza Ali Mohammad, known as the Bab, founder of the Babi religion from which the Baha’i faith emerged. Discuss
