- Quick lesson in Jewish Calendar 101: Back in the day, the calendar was set by the testimony of witnesses who would come to the Sanhedrin and testify that they saw the first appearance of the moon after the New Moon period of invisibility. Then problems arrived, such as Roman persecutions, inter-sect hostilities, etc., and eventually Hillel IV (i think it was him...maybe i got the number wrong) calculated a perpetual calendar which could be followed everywhere without the problems involved in getting the "official" witness-based proclamation. Before that, leap years would be ad-hoc'ly declared. The only reason why the Jewish Calendar is solilunar, and not purely lunar like the Muslim calendar, is that the Torah states that Passover has to be in the spring - so whenever it seemed like the lunar year was getting too far away from the solar year, the month Adar would be doubled in order to push the following month, Nisan, when Passover is, away from the winter and back into the springtime. The calendar is built on a 19-year cycle. 7 of those years, #s 3, 6, 8, 11, 14, 17, and 19 (known by the acronym GV"Hh 2DZ"Tt, pronounced [guaH adzat]) are leapyears, with the extra month Adar Rishon (Adar I). Notice that the "real" Adar is Adar Sheini (Adar II), as can be seen from the fact that the holidays that fall out in Adar are celebrated in Adar 2 in a leap year. So, the only difference between the "back in the day" calendar and the current calendar is that today all the intercalations are done set and mathematically instead of by witnesses' testimony. ObConCalendar: the Rokbeigalmki calendar is also solilunar, but doesn't need adjustments since the moon-cycle surrounding the New Year (the day after the Southern Hemisphere Winter Solstice) is split into two "months", one from the beginning until the solstice, the second from Dzu''Fa''Ri (new year's day) until the end. -Stephen (Steg) "sleep, like a fog, blew over him." ~ _gilgamesh_
