The Badi Solar Calendar

The Báb has, in His writings revealed in Arabic, divided the years following the date of His Revelation, into cycles of nineteen years each. Each cycle of nineteen years is called Váhid. Nineteen cycles constitute a period called Kull-i-Shay’. The numerical value of the word “Váhid” is nineteen. It signifies unity, and is symbolic of the unity of God. The numerical value of the “Kull-i-Shay’” is 361, and literally means “all things.”

Holy Days

The Baha’i Holy Days fall on the following days of the Badi Calendar: Naw-Ruz, 1 Baha; the Festival of Ridvan, 13 Jalal to 5 Jamal; the Declaration of the Bab, 8 Azamat; the Ascension of Baha’u’llah, 13 Azamat; the Martyrdom of the Bab, 17 Rahmat; the Day of the Covenant, 4 Qawl; and the Ascension of Abdu’l-Baha, 6 Qawl. These dates are fixed within the calendar and do not move – in other words, the Declaration of the Bab will always be joyously celebrated on 8 Azamat.

In contrast, there are Holy Days that move according to the movements of the moon. These Holy Days are the Birth of the Bab and the Birth of Baha’u’llah – which are also known as “The Twin Holy Days”. Beginning next year, they will be celebrated around the world in succession after the 8th new moon following Naw Ruz.

Up until this point, the Baha’is in the West observed these Holy Days according to the Gregorian calendar on October 20th and November 12th respectively and the Baha’is in the East celebrated them on the 1st and 2nd day of the Muslim month of Muharram. Beginning next year, we will all celebrate these special events at the same time.

In its letter about the universal implementation of the Badi Calendar, the Universal House of Justice also tells us of its legislation regarding when Naw-Ruz will occur. They write:

We have decided that Tihran, the birthplace of the Abha Beauty, will be the spot on the earth that will serve as the standard for determining, by means of astronomical computations from reliable sources, the moment of the vernal equinox in the northern hemisphere and thereby the day of Naw-Ruz for the Baha’i world.

Up until now, the Badi Calendar has been temporarily tethered to the Gregorian calendar and all of its months have been fixed. With this exciting legislation, the Badi Calendar will begin with the astronomically accurate vernal equinox, the first day of spring, and the entire year will be celebrated accordingly.
