Bahá'í leap year

A leap year in the The Bahá'í calendar occurs when an extra day is added in the last month. Leap years usually occur every 4 years.

Adding a leap day

The Bahá'í year begins on March 21 and is divided into 19 months of 19 days each, totaling 361 days. Four extra (intercalary) days are added to raise the number of days to 365 days to adjust the calendar.

A leap year in the Bahá'í calendar occurs when 5 days are added, instead of 4, in the last month, making it 366 days. The leap day is inserted in the days of Ayyam-i-ha, a period of intercalary days devoted to hospitality, charity and gift-giving from February 26 to March 1.

Most leap years in the Bahá'í calendar are at 4-year intervals, but 3 out of 4 years are non-leap, causing 8-year intervals at those points in time.
