Month

Among the Egyptians the month of thirty days each was in use long before the time of the Exodus, and formed the basis of their calculations. From the time of the institution of the Mosaic law the month among the Jews was lunar. The cycle of religious feasts depended on the moon. The commencement of a month was determined by the observation of the new moon. The number of months in the year was usually twelve (1 Kings 4:7; 1 Chr. 27:1-15); but every third year an additional month (ve-Adar) was inserted, so as to make the months coincide with the seasons. “The Hebrews and Phoenicians had no word for month save ’moon,’ and only saved their calendar from becoming vague like that of the Moslems by the interpolation of an additional month. There is no evidence at all that they ever used a true solar year such as the Egyptians possessed. The latter had twelve months of thirty days and five epagomenac or odd days.”, Palestine Quarterly, January 1889.

From the time of the institution of the Mosaic law downward the religious feasts commencing with the passover depended not simply on the month, but on the moon; the 14th of Abib was coincident with the full moon; and the new moons themselves were the occasions of regular festivals. (Numbers 10:10; 28:11-14) The commencement of the month was generally decided by observation of the new moon. The usual number of months in a year was twelve, as implied in (1 Kings 4:7; 1 Chronicles 27:1-15) but since twelve lunar months would make but 354 1/2 days, the years would be short twelve days of the short twelve days of the true year, and therefore it follows as a matter of course that an additional month must have been inserted about every third year, which would bring the number up to thirteen. No notice, however, is taken of this month in the Bible. In the modern Jewish calendar the intercalary month is introduced seven times in every nineteen years. The usual method of designating the months was by their numerical order, e.g. “the second month,” (Genesis 7:11) “the fourth month,” (2 Kings 25:3) and this was generally retained even when the names were given, e.g. “in the month Zif, which is the second month.” (1 Kings 6:1) The names of the months belong to two distinct periods. In the first place we have those peculiar to the period of Jewish independence, of which four only, even including Abib, which we hardly regard as a proper name are mentioned, viz.: Abib, in which the passover fell, (Exodus 13:4; 23:15; 34:18; 16:1) and which was established as the first month in commemoration of the exodus, (Exodus 12:2) Zif, the second month, (1 Kings 6:1,37) Bul, the eighth, (1 Kings 6:38) and Ethanim, the seventh. (1 Kings 6:38) and Ethanim, the seventh. (1 Kings 8:2) In the second place we have the names which prevailed subsequent to the Babylonish captivity; of these the following seven appear in the Bible: Nisan, the first, in which the passover was held, (Nehemiah 2:1; Esther 3:7) Sivan, the third (Esther 8:9) Bar. 1:8; Elul, the sixth, (Nehemiah 6:15) 1 Macc. 14:27; Chisleu, the ninth, (Nehemiah 1:1; Zechariah 7:1) 1 Macc. 1:54; Tebeth, the tenth, (Esther 2:16) Sebat, the eleventh, (Zechariah 1:7) 1 Macc. 16:14; and Adar, the twelfth. (Esther 3:7; 8:1) 2 Macc. 15:36. The names of the remaining five occur int he Talmud and other works; they were, Iyar, the second, Targum; (2 Chronicles 30:2) Tammuz, the fourth; Ab, the fifth; Tisri, the seventh; and Marcheshvan, the eighth. The name of the intercalary month was Ve-adar, i.e. the additional Adar. The identification of the jewish months with our own cannot be effected with precision on account of the variations that must inevitably exist between the lunar and the solar month. Nisan (or Abib) answers to March; Zif or Iyar to May; Sivan to June; Tammuz to July; Ab to August; Elul to September; Ethanim or Tisri to October; Bul or Marcheshvan to November; Chisleu to December; Tebeth to January; Sebat to February; and Adar to March.

MONTH. The ancient Hebrews called the months by their numbers - first month, second month, third month, etc. - though at the same time they also applied a special name to each month. This double nomenclature had nothing to do, however, with the double course of months which the Jews employed after leaving Egypt, one making the civil and the other the sacred year. The former commenced from the first new moon in October - and this was used in civil and agricultural concerns only - and the latter from the first new moon in April, because they left Egypt on the fifteenth of that month, and it was used in regulating the time of their feasts, etc. The prophets use this reckoning. "From the time of the institution of the Mosaic Law downward, the month appears to have been a lunar one. The cycle of religious feasts, commencing with the Passover, depended not simply on the month, but on the moon; and the new moons themselves were the occasions of regular festivals." Num 10:10; Num 28:11-14. The length of the month was regulated by the changes of the moon, but, twelve lunar months making only 354 days and 6 hours, the Jewish year was short of the true solar year by twelve days. To compensate for this difference, the Jews every three years intercalated a thirteenth month, which they called Ve-adar, the second Adar, and thus their lunar year became equal to the solar. The changes of the moon were carefully watched, and a formal announcement made of the appearance of the new moon by sound of trumpets and beacon-fires. Num 10:10; Ps 81:3. These observations were continued throughout Jewish history, though it is evident that the Jews were in possession of calculations by which the course of the moon could be predicted. 1 Sam 20:5, 1 Sam 20:24, 1 Sam 20:27. The names of the Hebrew months are as follows:
