Just because the lights were created on day 4 does not "prove" the year begins every year on day 4. Assuming the year did begin on day 4 in the first year of creation, after 365 1/4 days, the next solar year would begin. That would of necessity be on a different day of the week. However, it is an assumption to say the year always begins on day 4. It could have begun on day 1 which is why Elohim called it "DAY 1".
The mistake that many people make when observing the calendar mentioned in the
Bible, 1 Enoch, Jubilees, and the
DSS is that they seek to make YHWH's calendar fit into man made calendars and vice versa. The problem with this method is that any number ">" or "<" 364 Days will
never fit. This would cause the calendars to be in synch for a short period before having to readjust them again. The other mistake people make is that they fail to see that the calculations made in the calendar of YHWH is that they match up perfectly with the circuits of the Sun, Moon and stars, and the seasons and need no adjustment every ninteen years (or whatever years man made calendars use). In fact there are only two intercalation processes used at the end of each year:
1) The 4 Intercalary Days of the 4 Seasons added to the Sun.
2) The 10 Overplus Days accrued by the Sun and stars which are added to the Moon.
When people read
1 Enoch 74:9-12ff. they fail to see that the word "overplus"
does not equal "difference". And
1 Enoch makes it very clear that the Sun and stars complete the year in 360 Days (pre interacaltion) and the moon completes it in 354 Days (pre intercalation) but, where and when did the Sun and stars accrue an overplus of 6 Days?
01) 30 - 29 = 01
02) 30 - 30 = 00
03) 30 - 29 = 01
04) 30 - 30 = 00
05) 30 - 29 = 01
06) 30 - 30 = 00
07) 30 - 29 = 01
08) 30 - 30 = 00
09) 30 - 29 = 01
10) 30 - 30 = 00
11) 30 - 29 = 01
12) 30 - 30 = 00
We have now found where and when the 6 Overplus Days are located but,
1 Enoch also states that overplus Days of the Sun and stars amount to 10 Days each year so, when and where are they?
03) 31 - 29 = 2
06) 31 - 30 = 1
09) 31 - 29 = 2
12) 31 - 30 = 1
When we compare the 3rd, 6th, 9th, and 12th Months in our short list we see a +1 Day has been added to the 3rd, 6th, 9th, and 12th Months in our long list. We have now shown and proven when, where, and why the Sun and stars have an overplus of 10 Days each year.
We see then that the Moon is to complete the year in 360 Days along with the Sun and stars (pre intercaltion) and 364 Days (post intercalation):
End of Year (Pre Intercalation)
Sun and stars = 360 Days + 6 Overplus Days
Moon = 354 Days
End of Year (Post Intercalation)
Sun and stars = 366 Days + 4 Overplus Days + 4 Intercalary Days = 374 Days - 10 Overplus Days = 364 Days
Moon = 354 Days + 10 Overplus Days = 364 Days
The Sun, Moon, and stars complete the year in 364 Days as stated in
1 Enoch, DSS, and
Jubilees.
