So in light of Leo's post (thanks, btw. It took me about 4 repeat readings but I finally got it!) I guess the question to ask then is, Is the 2520 days representative of seven years or is it literally 2520 consecutive days?
Representative of seven years? In other words, representative of 2556.75 consecutive days? Then why is it applied by the Society as a literal 2520 consecutive years?
M.J...As you know, there is no stated length of 2,520 days in the Bible. There are the lengths of 1,290 and 1,335 days in Daniel, and the 1,260 days in Revelation, which both tally the length of a period by counting only monthly days. In the case of Daniel, the period of "a time, times, and half a time" in 7:25 (equivalent to the "half-week" in ch. 9, in which a week of years is a sabbatical period) is associated with the 1,290 and 1,335 days of ch. 12, but these latter two durations add in an extra month and month and a half for further events to happen after the conclusion of the seventieth sabbatical cycle. These durations are transparently adding together solar months without regard to the extramonthly days that figure in the yearly reckoning, instead of the monthly reckoning (i.e. the equinoxes and solstices). Only in ch. 8 of Daniel do we find a reckoning of consecutive days (or rather, of the two Tamid sacrifices held twice a day everyday), but this was of only a portion of the 3 1/2 years. In the Priestly document of the Pentateuch, Daniel (and Revelation in imitation), and the "Book of Luminaries" of 1 Enoch, the solstices and equinoxes were not included in the months....they stand in between the seasons (each season containing three 30-day months), as intercalary indicators of the seasons, such that the year would have the following format: 1 + (30 + 30 + 30) + 1 + (30 + 30 + 30) + 1 + (30 + 30 + 30) + 1 + (30 + 30 + 30) = 364 days. This calendar was sabbatical such there would be 52 weeks per year (364 / 7 = 52), with the sabbaths and festivals falling on the same day of the week each year. By the time of the second century BC, the solar calendar used by the author of Jubilees and the Qumran community began to include these extramonthly days within the monthly reckoning, such that each season would be 30 + 30+ 31. Since the Society utilizes Daniel and Revelation to invent their period of 2,520 days, a period of "seven times" if at all double the length of the 3 1/2 "times" of Daniel should similarly include these extramonthly days if they want to spell out the actual length of the period. Seven times in the Danielic solar calendar would be 360 x 7 = 2,520 days + 28 days (i.e. 4 extra days x 7) + 7 days (the extra week added in at the end of a sabbatical cycle, so that the spring equinox would fall on the right day) = 2,555 days.
The Society of course is totally unaware of the dynamics of the ancient solar calendar, knowing only of the lunar calendar (which is the basis of the modern Jewish calendar). They believe that the 360-day year was a special "prophetic calendar" or a rough abstraction of the alternating 29-day, 30-day lunar calendar, but this is just ignorance of ancient Jewish calendrical practices. The reality was that this was a sabbatical priestly calendar and thus had to amount to 364 consecutive days each year, so that the year would have an even number of 52 weeks. Those 4 extra days were included within the year, but not counted in the monthly count, which had even 30-day months, since these were special days heralding the seasons.
