The Hebrew calendar is dated from the creation, which is supposed to have taken place 3761 years before Christ. Hence, to find the number of cycles elapsed since the creation, also the number in the cycle, we have the following rule: Add 3761 to the date, divide the sum by nineteen; the quotient is the number of cycles, and the remainder is the number in the cycle. Should there be no remainder, the proposed year is, of course, the last or nineteenth of the cycle. Thus, for the year 1883, we have 1883 + 3761 / 19 = 297, remainder 1; therefore, 297 is the number of cycles, and 1 the number in the cycle. Again, for the year 1893, we have 1893 + 3761 / 19 = 297, remainder 11; therefore 297 is the number of cycles, and 11 the number in the cycle. Again for the year 1901, we have 1901 + 3761 / 19 = 298, remainder 0; therefore 298 is the number of cycles, and 19 the last of the cycle. Hence it may be seen that the present cycle commenced with 1883, that 11 is the number in the cycle for the present year 1893, also that the cycle ends with 1901; so that the next cycle commences with 1902. If the remainder after dividing by nineteen be 3, 6, 8, 11, 14, 17 or 19 (0), the year is intercalary or embolismic, consisting of 384 days; if otherwise it is ordinary, containing only 354 days; so that in a cycle of nineteen years, we have twelve ordinary years of 354 days each, and seven embolismic years of 384 days each. But, in either case, the year is sometimes made a day more, and sometimes a day less, in order that certain festivals may fall on proper days of the week for their due observance. Hence the ordinary year may consist of 353, 354 or 355 days, and the embolismic year of 383, 384 or 385 days. In the modern Jewish calendar the New Year commences with the new moon of Tisri, which may happen as early as the 5th of September or as late as the 5th of October. The new moon of Nisan, which is the first month in the Sacred year, may happen as early as the 11th of March or as late as the 11th of April. It should be borne in mind that the names of the months Abib, Zif, Ethanim and Bul were superceded after the captivity, by Nisan, Iyar, Tisri and Hesvan or Marchesvan; also the name of the third month in the civil year, Chisleu in the Bible, Kislev in the modern Jewish calendar. In table No. 1 we have the names of the months in numerical order, also the number of days in each month. Though the months consist of 30 and 29 days alternately, yet, in the embolismic year, Adar, which in common years has 29 days, is given 30 days, and 2d Adar 29; so that two months of 30 days come together. Table No. 2 shows the earliest and the latest possible date of the new moons of each of the months respectively. TABLE 1. HEBREW MONTHS.
