THE BAHÁ’Í CALENDARNormally, Bahá’ís all over the world use the calendar most common to the society in which they live. The Bahá’ís of Marin County do this as well. Here, we show Bahá’í activities on the Gregorian version of the Christian calendar – the “normal” calendar for our area. However, every religion has its own calendar: the Jewish calendar, for example. And the Bahá’í Faith has its own calendar as well.
The Bahá'í calendar, also called the Badí‘ calendar (badí‘ means wondrous or unique), is a solar calendar with years composed of 19 months of 19 days each (361 days) plus an extra period of "Intercalary Days". Years begin at Naw-Rúz, on the vernal equinox, coinciding with March 20 or 21, and the days begin at sunset, as do Jewish “days.”
