Start of Year 1 BE

Year 1 BE began at sundown on 20 March 1844. Years in the Baháʼí calendar are counted from Thursday 21 March 1844, the beginning of the Baháʼí Era or Badíʿ Era. The first year is dated from 1844 CE, the year in which the Báb began teaching. In later practice the calendar was synchronized to the Gregorian calendar by starting the year at sunset on March 20, regardless of when the vernal equinox technically occurs, so that the extra day of a leap year occurred simultaneously in both calendars. No supplied passage states where the calendar's start was observed.
