Dating of the flood
This means Noah was 502 when Shem was born 98 years earlier.However, Genesis says: This is a discrepancy of two years.The calendar changed to the Lunisolar Autumn Calendar after the Flood when the first visible crescent new moon appeared following the collapse of the water canopy, when Noah was 601 years old.This meant that the last 299 years of Noah's life were counted in the Lunisolar Autumn Calendar.Common sense would dictate that if you had a large number of generations, that the age of a father at the birth of a son would be some age plus an average of 6 months or year.Neglecting this factor can produce an appreciable error.
Since the points fortunately line up, it provides strong evidence that we have found back-to-back Sabbatical Years indicating the 49th and 50th years of the 49 year Jubilee cycle. No other orientation or matching up would result in as many dates falling on Sabbatical/Jubilee Years. Interestingly enough, the phrase appointed time is used 22 times in the New International Version of the Bible. In other words, when it says that Adam was 130 years old when he had Seth, does it mean he was "And Adam lived one hundred and thirty years and fathered a son in his own likeness, according to his image, and called his name Seth." (The Interlinear Bible, Hebrew-Greek-English, with literal English translation)Given this then, we must take into consideration another factor that other calculations of the date of Creation have not taken into consideration.
However, it is difficult to substantiate this date, but it has served as an adequate estimate of the date of Creation for some time.
Based upon the genealogy of the patriarchs as contained in Scripture, once one has determined the date of the Exodus of the Israelites from Egypt, one should be able to arrive at a reasonably close determination for the Date of Creation.
Beside the above date pairs, ALL prophecies containing prophetic dates interpreted using the "day for a year" principle (see Num. 4:5, 6) have either a beginning or end point on a Sabbatical Year! The son of a patriarch would rarely be born during the same month or on the same day as his father's birthday.
These include the:70 sevens or 490 year prophecy of Dan. In fact, the father could be anywhere from 1 day to nearly 12 months older than the age given in the Bible states.Noah) or anniversary of an event (the migration into Egypt).
