After that, in the ninth week, the righteous judgment will be revealed to the whole world [re-establishment of the nation of Israel], and all the works of the godless will vanish from the earth, and the world will be written down for destruction [Great Tribulation], and all men will look to the path of integrity [beginning of the Millennium]. Enoch 91b:14
The “Righteous Judgment” that begins the "destruction" is the punishment of the wicked in the seven-year Tribulation. The "path of integrity" is the 1000-year Reign of the Messiah on earth. The “birth pangs” of this period begin with the establishment of the nation of Israel.
Israel was reestablished in 5873 AM (AD 1948). The seven-year Tribulation should be the seven years prior to the start of the Millennial Reign. The Zadok priests believed that the Millennial Reign would begin in the year 6000 AM (AD 2075).
It is interesting to note that if the year 6000 AM is March 2075 to March 2076, and if that is the start of the one thousand years, then the beginning of the seven-year tribulation period could be seven years prior, March 2067 to March 2068. If God gave us a 120-year warning period like He did the pre-flood world in Genesis 6:3, then 2068 minus 120 years would have been AD 1948. This was the year of the reestablishment of the nation of Israel. Right on time!
The ninth week would be 5601-6300 AM (AD 1676-2375).
