What is the Bah Calendar?
Bah’s have a distinct calendar, with nineteen months of nineteen days, plus four (five in leap years) intercalary days that Bah’s call Ayym’i’H (thus, 19×19+4=365). The year begins with Naw-Ruz on March 21 (the first day of Spring), following nineteen days of daytime fasting (info). The months are named for the attributes of God. There are also nine holy days throughout the year, including the birthday of Bah’u’llh (November 12), the birthday of the Bb (October 20), and the declaration of the Bb (May 23). More details on the Bah’ calendar can be found here. We are now in Bah’ year 166.
