Understanding the significance of the day counts based on year type:

The easiest way to look at this is that all the timekeepers were created by God for signs:

Genesis 1:14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years.

The sidereal year is a longer year, and is not aligned with the season, which is a difference of about 30 days over a 2,018 year period. However, the sidereal year is a timekeeper and maybe used for signs, Gen 1:14. The day accumulation of sidereal years as a sign may be used without implying that the equivalent number of days must be added to our equinox or seasonal based calendar (tropical year). --see previous study

The equinox year based calendar (like our gregorian) and the lunar seasonal based (Jewish) are calendars that make adjustments (leap years) to stay in line with the seasons (equinoxes). The lunar calendar however because of it shorter year (354 days) requires a larger leap of an extra month about every three years to keep it aligned to the seasons.

The equinox year based calendars and lunar based are for signs also, but their actual total day counts reference to actual events (not only just for signs).

• When the Passover occurred in 33 AD, it was actually early Spring season.
• When Pentecost occured in 33 AD, it was actually late Spring season.
• When Babylon was destroyed it was actually Fall 539 BC.
• When the Flood ended it was actually the Fall 4989 BC.

In addition, God appointed the moon to govern the seasons:

Psalms 104:19 He appointed the moon for seasons: the sun knoweth his going down.

The Lunar based calender, interestingly every 19 years exactly matches the same day count of our solar equinox based calender (gregorian):

Background:

:

Metonic cycle (Britannica 2003)

Metonic cycle in chronology, a period of 19 years in which there are 235 lunations, or synodic months, after which the Moon's phases recur on the same days of the solar year, or year of the seasons. The cycle was discovered by Meton (fl. 432 BC), an Athenian astronomer. Computation from modern data shows that 235 lunations are 6,939 days, 16.5 hours; and 19 solar years, 6,939 days, 14.5 hours.

This can be tested for yourself, if you have access to Jewish Calendars or use this link>>http://www.fourmilab.ch/documents/calendar/ .

Go to Tishri 15, 1993, it falls on September 30, 1993.

Go to Tishri 15, 2012, it falls on October 1, 2012

19 years is also the total time of possible Great Tribulation in our day as this was the total length of Jacob's Great Tribulation 1879 BC (Start of dearth) plus 19 years equals 1860 BC (End of Jacob's Great Tribulation). There are 3872 years from 1879 BC to 1993/1994 AD, which has factors of (88 [3 months to Harvest/God decides whether to rain or not to rain on the city] X 11 [last hour] X 4 [complete end]).

The 1993 (planting/plowing/ rain season) + 19 years = 2012 AD.

The year 1993 /1994 is the 13,005th year of the earth's existence (153 X 17 X 5), completion of the Pentecost Harvest and the year that begins spiritual famine in our local congregations.

John 21:11 Simon Peter went up, and drew the net to land full of great fishes, an hundred and fifty and three: and for all there were so many, yet was not the net broken.

• Rain Season - as the precursor to harvest  - 1st 6 months of a harvest year(early and latter rain,plowing and planting done during this time)
• Harvest Season - the 2nd 6 months of a harvest year

God's spiritual harvest (salvation) is based on the seasons and share the same timing associated with physical harvest as we see in 1Corinthians 3:

1Corinthians 3:6 I have planted, Apollos watered; but God gave the increase.

1Corinthians 3:7 So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase.

1Corinthians 3:8 Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.

1Corinthians 3:9 For we are labourers together with God: ye are God's husbandry, ye are God's building.

The Bible links the rain season with its harvest season.

James 5:7 Be patient therefore, brethren, unto the coming of the Lord. Behold, the husbandman waiteth for the precious fruit of the earth, and hath long patience for it, until he receive the early and latter rain.

18 years is also consistent with the Great Tribulation in Jacob's Days owed to the end of harvest season in Canaan in 1878 BC (typified the end of the Pentecost Harvest). Jacob was 128* in the year 1879-1878 BC.

1993 (Rain Season) + 19 = 2012 AD or 1994 (Harvest Season ) + 18 = 2012 AD

*There are 128 day or 18 weeks from Pentecost to the Feast of Ingathering

The Coming of Christ (Firstfuit) in 7 BC is identified the beginning of Harvest:

1Corinthians 15:23 But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming.

1Corinthians 15:24 Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power.

The end of Harvest is associatd with the 2nd coming of Christ and the end of the World:

The end of Harvest is defined by the Bible when there is no more crops  to harvest this commences the  start of the feast of Ingathering not the completion of the feast of Tabernacles.

Exodus 23:16 And the feast of harvest, the firstfruits of thy labours, which thou hast sown in the field: and the feast of ingathering, which is in the end of the year, when thou hast gathered in thy labours out of the field. 

The time keepers are destroyed at Christ's coming at  the end of Harvest. After the 19 years of Jacob’s Great Tribulation  or when the seventy years was accomplished  for which Great Tribulation ended  in  Babylon 539 BC, there are no intervening events between the end of Great Tribulation and the spiritual picture of Christ’s  Return.

Matthew 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: 

Matthew 24:30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. 

Matthew 24:31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.

Feast of Ingathering (Tabernacles) spiritually represents an eternal celebration:

Leviticus 23:40 And ye shall take you on the first day the boughs of goodly trees, branches of palm trees, and the boughs of thick trees, and willows of the brook; and ye shall rejoice before the LORD your God seven days. 

Leviticus 23:41 And ye shall keep it a feast unto the LORD seven days in the year. It shall be a statute for ever in your generations: ye shall celebrate it in the seventh month.

Revelation 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.

Revelation 21:2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.

Revelation 21:3 And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God.

From the birth of the Lord Jesus on October 1, 7 BC (Day of Atonement) to October 1, 2012 AD (the Feast of Ingathering) there is a total of 737,058 days (Gregorian Vernal Equinox Based). The factors for the number 737,058 are 3 (purpose/established by God), 7 X 7 [perfect completion/Sabbath (end of Harvest Activity)], 23 (judgment) 218 (Total of male Judean clan which returned from the Babylonian exile with Zerubbabel, Ezra 8:9 ).

3 X 7 X 7 X 23 X 218 = 737,058 DAYS

OCTOBER 1, 7 BC TO OCTOBER 1, 2012 = 737,058 DAYS

The number 3 is used to illustrate Purpose or something established by God:

Deuteronomy 19:15 One witness shall not rise up against a man for any iniquity, or for any sin, in any sin that he sinneth: at the mouth of two witnesses, or at the mouth of three witnesses, shall the matter be established.

Joshua 1:11 Pass through the host, and command the people, saying, Prepare you victuals; for within three days ye shall pass over this Jordan, to go in to possess the land, which the LORD your God giveth you to possess it.

Mark 8:31 And he began to teach them, that the Son of man must suffer many things, and be rejected of the elders, and of the chief priests, and scribes, and be killed, and after three days rise again.

The numbers 7X7 or 49 are identified with perfect completion/Sabbath (end of Harvest Activity):

Leviticus 25:4 But in the seventh year shall be a sabbath of rest unto the land, a sabbath for the LORD: thou shalt neither sow thy field, nor prune thy vineyard.

Leviticus 25:5 That which groweth of its own accord of thy harvest thou shalt not reap, neither gather the grapes of thy vine undressed: for it is a year of rest unto the land.

Leviticus 25:6 And the sabbath of the land shall be meat for you; for thee, and for thy servant, and for thy maid, and for thy hired servant, and for thy stranger that sojourneth with thee,

Leviticus 25:7 And for thy cattle, and for the beast that are in thy land, shall all the increase thereof be meat.

Leviticus 25:8 And thou shalt number seven sabbaths of years unto thee, seven times seven years; and the space of the seven sabbaths of years shall be unto thee forty and nine years.

The Number 23 is identified with judgment

1Corinthians 10:8 Neither let us commit fornication, as some of them committed, and fell in one day three and twenty thousand.

Judgment befalls upon the unsaved world at the End of Harvest:

There is no harvest activity (gathering and reaping) after Christ makes an appearance which coincides with the end of the  harvest  and the  start of the Celebration of that Feast of Ingathering (Tabernacles)

Matthew 13:27 So the servants of the householder came and said unto him, Sir, didst not thou sow good seed in thy field? from whence then hath it tares? 

Matthew 13:28 He said unto them, An enemy hath done this. The servants said unto him, Wilt thou then that we go and gather them up? 

Matthew 13:29 But he said, Nay; lest while ye gather up the tares, ye root up also the wheat with them. 

Matthew 13:30 Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn. 

Matthew 13:39 The enemy that sowed them is the devil; the harvest is the end of the world; and the reapers are the angels. 

Matthew 13:40 As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world. 

The end of Harvest is defined by the Bible when there is no more crops  to harvest this commences the start of the feast of Ingathering not at the completion of the feast of Tabernacles.

Exodus 23:16 And the feast of harvest, the firstfruits of thy labours, which thou hast sown in the field: and the feast of ingathering, which is in the end of the year, when thou hast gathered in thy labours out of the field. 

The number 218 eponymous ancestor of a Judean clan which returned from the Babylonian exile with Zerubbabel. There is a spiritual correlation between the year of the Babylonian Jewish Exiles Return under Zerubbabel in 537 BC and the year 2012 AD. There are 2,548 years from 537 BC to the year 2012 AD. The factors of 2,548 are: 4 (complete end) X 7 X 7 [perfect completion/Sabbath (end of Harvest Activity)] X 13 (Super-fullness), a separate study related to this subject will be presented later.

Key verse

Ezra 8:9 Of the sons of Joab; Obadiah the son of Jehiel, and with him two hundred and eighteen males.

The grown males were commanded to appear for the Feast of Tabernacles:

Deuteronomy 16:16 Three times in a year shall all thy males appear before the LORD thy God in the place which he shall choose; in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles: and they shall not appear before the LORD empty:

Jewish Exiles (including the sons of Joab - whom typified he true believers in Christ) Return under Zerubbabel in 537 BC celebrated the Feast of Tabernacles:

Ezra 3:2 Then stood up Jeshua the son of Jozadak, and his brethren the priests, and Zerubbabel the son of Shealtiel, and his brethren, and builded the altar of the God of Israel, to offer burnt offerings thereon, as it is written in the law of Moses the man of God.

Ezra 3:3 And they set the altar upon his bases; for fear was upon them because of the people of those countries: and they offered burnt offerings thereon unto the LORD, even burnt offerings morning and evening.

Ezra 3:4 They kept also the feast of tabernacles, as it is written, and offered the daily burnt offerings by number, according to the custom, as the duty of every day required;

Ezra 3:5 And afterward offered the continual burnt offering, both of the new moons, and of all the set feasts of the LORD that were consecrated, and of every one that willingly offered a freewill offering unto the LORD.
