Our Gregorian calendar aims to keep the vernal equinox on or close to March 21; hence, it follows the vernal equinox year. The average length of the Gregorian year is 365.2425 days. There is only a difference of 0.000302 (0.2425-0.242198) between the Tropical year (vernal equinox year) and a Gregorian Year. At this fractional difference, it would take 3,311 years just to generate one day of difference.

• There are 3,871 years from September 18, 1860 BC (Feast of Ingathering ) to October 1, 2012 BC. (12 days after September 18, 2012 (Feast of Ingathering - Tishri 15 begins after 6 PM on September 30)

The number 16 (weeks) is identified with 4 months (months of 29 days) to harvest/ 29 x 4 =116 days or 29.5 X 4 = 118, 118 or 116 days divided by 7 (7 days per week) = 16 (weeks):

In Genesis 1:14, the establishment of the lunar framework for years and seasons was established at creation, as the moon was the light that determined the length of the month (29.5 days (1 lunar month) x 12 = 354 days (a lunar year).

The same Hebrew word "chodesh" from one new moon to another new moon [29.5 days] in Isaiah 66:23 is used in Genesis 8:5 translated as month.
 

Genesis 8:5 And the waters decreased continually until the tenth month: in the tenth month [2320 chodesh], on the first day of the month, were the tops of the mountains seen.

Isaiah 66:23 And it shall come to pass, that from one new moon [2320 chodesh] to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD.

God specifically identifies the Final Harvest being associated with 4 months in John 4:35 , Four months is a period of 118,117 or 116 days or 16 weeks, for example:
 

118 Days (29.5 times 4)

116 Days (29 times 4) a lunar month may consist of either 29 or 30 days, since 29 days may also be considered the length of a month. The number of days for 4 months that contain 29 days may also equal 116 days.

16 Weeks (118* days, 117 days or 116 days divided by 7

*118th day is a Sabbath Tishri [7th month] 15th [day], which would not be a harvest activity day (but the beginning of an eternal celebration of the end of harvest):

Leviticus 23:39 Also in the fifteenth day of the seventh month, when ye have gathered in the fruit of the land, ye shall keep a feast unto the LORD seven days: on the first day shall be a sabbath, and on the eighth day shall be a sabbath.

The final harvest that occurs during both periods of typified Great Tribulation (Destruction of Judah and Dearth in Canaan) are identified with 4 month (multiples of 4) and occurs outside of the normal domicile of the true believer (outside physical Judah, outside Canaan and in our day outside the physical organized churches as Satan rules the physical organized churches the former domicile of the true believers during the Period of Great Tribulation

Destruction of Judah by Flood (Babylon) Walls burned and true believers (typified by the Jews) in Captivity-Final Harvest for true believers only in physical Babylon,
 

Jeremiah 29:28 For therefore he sent unto us in Babylon, saying, This captivity is long: build ye houses, and dwell in them; and plant gardens, and eat the fruit of them.

Nehemiah 1:3 And they said unto me, The remnant that are left of the captivity there in the province are in great affliction and reproach: the wall of Jerusalem also is broken down, and the gates thereof are burned with fire.

Destruction of Canaan by dearth(drought and famine). Final Harvest occurs outside Canaan (in physical Egypt)
 

Acts 7:11 Now there came a dearth over all the land of Egypt and Chanaan, and great affliction:[2347. thlipsis] and our fathers found no sustenance.

Destruction of Physical Church by Satan (typified by Jezebel/ -ruler of northern Kingdom). The coming of the Lord is contingent upon Satan controlling the physical organized churches, which are the only physical temples on earth that are supposedly married to Christ (but in actually are not as only the true believer typified as wheat [Matthew 13:25] present in these physical churches are saved while tares [Matthew 13:25] who are also members of these physical organized churches are not )
 

2Thessalonians 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,

2Thessalonians 2:2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.

2Thessalonians 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;

2Thessalonians 2:4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God

Satan who becomes the teacher/ruler in all the physical churches (typified by the Church of Thyatira) during the time of Great Tribulation results in those who stay in these physical organized churches to commit spiritual fornication, Revelation 2:20.

Revelation 2:18 And unto the angel of the church in Thyatira write; These things saith the Son of God, who hath his eyes like unto a flame of fire, and his feet are like fine brass;

Revelation 2:19 I know thy works, and charity, and service, and faith, and thy patience, and thy works; and the last to be more than the first.

Revelation 2:20 Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols.

Revelation 2:21 And I gave her space to repent of her fornication; and she repented not.

Revelation 2:22 Behold, I will cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of their deeds.

True believers are admonished to remove themselves from the physical organized churches which are spiritually serving Satan or Spiritual Babylon, as Satan is the de facto ruler of all the physical organized churches in total during the period of Great Tribulation.
 

Revelation 2:8 And unto the angel of the church in Smyrna write; These things saith the first and the last, which was dead, and is alive;

Revelation 2:9 I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.

Once Satan gains rulership control of the physical organized churches ["where Satan’s seat is", Revelation 2:13] they are Spiritually Babylon **
 

Satan's seat of worship (rulership) historically has been the physical organized churches as evidenced by the church of Pergamos, but his rulership is in total in the physical organized churches during the period of Great Tribulation. As we see the physical organized churches failure to repent "And I gave her space to repent of her fornication; and she repented not" is the causative effect of "Great Tribulation" in the church of Thyatira,

Revelation 2:12 And to the angel of the church in Pergamos write; These things saith he which hath the sharp sword with two edges;

Revelation 2:13 I know thy works, and where thou dwellest, even where Satan’s seat is: and thou holdest fast my name, and hast not denied my faith, even in those days wherein Antipas was my faithful martyr, who was slain among you, where Satan dwelleth.

Spiritual Babylon is place of worship (drunk of the wine of the wrath of her fornication,)
 

Revelation 18:2 And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird.

Revelation 18:3 For all nations have drunk of the wine of the wrath of her fornication, and the kings of the earth have committed fornication with her, and the merchants of the earth are waxed rich through the abundance of her delicacies.

Revelation 18:4 And I heard another voice from heaven, saying, Come out of her, my people, that ye be not partakers of her sins, and that ye receive not of her plagues.

**Note: Spiritual Babylon is associated with the religious worship of Satan which is deceptive in nature, since Satan and the worship of Satan can transform into what appears to be religious, holy and associated with Christ (but in actuality is not) The physical organized churches during our time of Great Tribulation appears to be religious, holy, and associated with Christ (but in actuality is not)
 

2Corinthians 11:13 For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.

2Corinthians 11:14 And no marvel; for Satan himself is transformed into an angel of light.

2Corinthians 11:15 Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
