12. Herodiez 7th July.

To complete the year five complementary days are added in common
years, and six in leap years.

_The Mahommedan Era, or Era of the Hegira._--The era in use among the
Turks, Arabs and other Mahommedan nations is that of the _Hegira_ or
_Hejra_, the flight of the prophet from Mecca to Medina, 622 A.D. Its
commencement, however, does not, as is sometimes stated, coincide with
the very day of the flight, but precedes it by sixty-eight days. The
prophet, after leaving Mecca, to escape the pursuit of his enemies, the
Koreishites, hid himself with his friend Abubekr in a cave near Mecca,
and there lay for three days. The departure from the cave and setting
out on the way to Medina is assigned to the ninth day of the third
month, Rabia I.--corresponding to the 22nd of September of the year 622
A.D. The era begins from the first day of the month of Muharram
preceding the flight, or first day of that Arabian year which coincides
with Friday, July 16, 622 A.D. It is necessary to remember that by
astronomers and by some historians the era is assigned to the preceding
day, July 15. It is stated by D'Herbelot that the era of the Hegira was
instituted by Omar, the second caliph, in imitation of the Christian era
of the martyrs.

_Era of Yazdegerd, or Persian or Jelalaean Era._--This era begins with
the elevation of Yazdegerd III. to the throne of Persia, on the 16th of
June in the year of our era 632. Till the year 1079 the Persian year
resembled that of the ancient Egyptians, consisting of 365 days without
intercalation; but at that time the Persian calendar was reformed by
Jel[=a]l ud-D[=i]n Malik Shah, sultan of Khorasan, and a method of
intercalation adopted which, though less convenient, is considerably
more accurate than the Julian. The intercalary period is 33 years,--one
day being added to the common year seven times successively at the end
of four years, and the eighth intercalation being deferred till the end
of the fifth year. This era was at one period universally adopted in
Persia, and it still continues to be followed by the Parsees of India.
The months consist of thirty days each, and each day is distinguished by
a different name. According to Alfergani, the names of the Persian
months are as follows:--

Afrudin-meh. Merded-meh. Adar-meh.
Ardisascht-meh. Schaharir-meh. Di-meh.
Cardi-meh. Mahar-meh. Behen-meh.
