It's possible that because we're in the LAST Jubilee of this Age, Tabernacles, the feast of the 7th Month, was delayed for 4 Months to be fulfilled in the 11th Month we're now in. Let's consider the evidence.

"On the last day, that great day [day 22] of the feast..." [John 7:37]

Day 22 of the 7th Month is called "THAT GREAT DAY. It fell on the 12th of October 2017. 

Day 22 of the 11th Month is also called THE GREAT DAY. It falls on the 7th of February 2018. 

"The sun shall be turned into darkness [21st August 2017], and the moon into blood [day 15][31st January 2018], BEFORE the coming of the GREAT and awesome day [day 22][7th of February 2018] of the Lord. And it shall come to pass that whoever calls on the name of the Lord shall be saved." [Acts 2:20,21]

"After these things I looked, and behold, a great multitude which no one could number, of all nations, tribes, peoples, and tongues, standing before the throne and before the Lamb, clothed with white robes, with PALM BRANCHES in their hands...Then one of the elders answered, saying to me, “Who are these arrayed in white robes, and where did they come from?” And I said to him, “Sir, you know.” So he said to me, “These are the ones who come out of the great tribulation, and washed their robes and made them white in the blood of the Lamb." [Rev.7:9,13,14]

I believe we're among this great multitude who will be taken up into heaven, in the Rapture, to stand before the throne of our Lord and God, Jesus Christ! The palm branches in their hands, point to the feast of the 7th Month which appears to have been delayed for 4 Months in order to be fulfilled NOW, in the 11 Month!!!

‘Also on the fifteenth day of the seventh month, when you have gathered in the fruit of the land, you shall keep the feast of the Lord for seven days [day 16 - day 22]; on the first day [day 15] there shall be a sabbath-rest, and on the eighth day [day 22] a sabbath-rest. And you shall take for yourselves on the first day [day 15] the fruit of beautiful trees, BRANCHES OF PALM TREES, the boughs of leafy trees, and willows of the brook; and you shall rejoice before the Lord your God for seven days [day 16 - day 22]. You shall keep it as a feast to the Lord for seven days [day 16 - day 22] in the year. It shall be a statute forever in your generations. You shall celebrate it in the seventh month. You shall dwell in booths for seven days [day 16 - day 22]. All who are native Israelites shall dwell in booths..." [Lev.23:39-42]

"And they found written in the Law, which the Lord had commanded by Moses, that the children of Israel should dwell in booths during the feast of the seventh month, and that they should announce and proclaim in all their cities and in Jerusalem, saying, “Go out to the mountain, and bring olive branches, branches of oil trees, myrtle branches, palm branches, and branches of leafy trees, to make booths, as it is written.”

"Then the people went out and brought them and made themselves booths, each one on the roof of his house, or in their courtyards or the courts of the house of God, and in the open square of the Water Gate and in the open square of the Gate of Ephraim. So the whole assembly of those who had returned from the captivity made booths and sat under the booths; for since the days of Joshua the son of Nun until that day [day 15] the children of Israel had not done so. And there was very great gladness. Also day by day, from the first day [day 15] until the last day [day 22], he read from the Book of the Law of God. And they kept the feast seven days [day 16 -day 22]; and on the eighth day [day 22] there was a sacred assembly, according to the prescribed manner. [Neh.8:14-18]

The Blood Moon, scheduled to occur on the 31st of January, 2018, could very well be the Lord's way of giving us a sign in the heavens that the feast of the 7th Month is going to be observed in the 11th Month of the Jubilee! I will definitely be glorifying and celebrating the Lord, with with fasting, from the 31st of January, 2018, until the 7th of February, 2018. The Lord wants to find us glorifying Him on the Day He returns for us. This is why the Apostle Paul wrote: "On that Day, when he comes to be glorified by his holy people and admired by all who have trusted, you will be among them..." [2 Thess.1:10][CJB]

The 7th Month.

The Lord is sovereign and He can do whatever He so pleases. And If He's chosen to delay the celebration of feast of tabernacles for 4 Months, maybe include more people in the Rapture, who are we to question His decision? May the Lord's perfect will be done!
