Ayyám-i-Há or Intercalary Days are celebrated by people of the Bahá'í faith. At this time, days are added to the Bahá'í calendar to maintain their solar calendar.
Why is it important?
The Bahá╩╝í Faith is a relatively new religion teaching the essential worth of all religions and the unity of all people. Established by Bahá╩╝u'lláh in the 19th century, it initially developed in Iran and parts of the Middle East, where it has faced ongoing persecution since its inception.
Ayyám-i-Há is a period of intercalary days in the Bahá╩╝í calendar, when Bahá╩╝ís celebrate the Festival of Ayyám-i-Há. The four or five days of this period are inserted between the last two months of the calendar (Mulk and ╩╗Alá╩╝). The length of Ayyám-i-Há varies according to the timing of the following vernal equinox so that the next year always starts on the vernal equinox.
Intercalary days are observed with gift-giving, special acts of charity, and preparation for the fasting that precedes the New Year.
