Heb. shanah, meaning "repetition" or "revolution" (Gen. 1:14; 5:3
). Among the ancient Egyptians the year
consisted of twelve months of thirty days each, with five days added to make it a complete revolution of the earth
round the sun.
The Jews reckoned the year in two ways, (1) according to a sacred calendar, in which the year began about the time of the vernal equinox, with the month Abib;
and (2) according to a civil calendar, in which the year began about the time of the autumnal equinox, with the month Nisan.
The month Tisri
is now the beginning of the Jewish year.
