Holy Days, Anniversaries, and Feast Days
The Bahá'í year consists of 19 months of 19 days each (i.e., 361 days), with the addition of certain 'intercalary days' (four in ordinary and five in leap years) between the eighteenth and nineteenth months in order to adjust the calendar to the solar year. The Bahá'í New Year, like the ancient Persian New Year, is astronomically fixed, commencing at the March equinox (21 March).
