Bahá'í calendar

The Bahá'í calendar, also called the Badí‘ calendar (badí‘ means wondrous or unique), used by Bábism and the Bahá'í Faith, is a solar calendar with years composed of 19 months of 19 days each, (361 days) plus an extra period of "Intercalary Days". Years in the calendar begin at the vernal equinox, and are counted with the date notation of BE (Bahá'í Era), with 21 March 1844 CE being the first day of the first year, the year the Báb proclaimed his religion.
