If there are really 2,520 days to the tribulation period of 1,260 days + the Great Tribulation of 1,260 and Jesus returns to Earth on the 1st day of Feast of Trumpets, 9/06/2032, then 1st day of the 2,520 day period would be on the 8th and last day of the Feast of Tabernacles, 10/14/2025. 10/14/2025 thru 9/06/2032 are exactly 2,520 days. Please remember that the years 2028 and 2032 are leap years and each of them has 1 extra day.
Begin by counting the 1st day of the 2,520 days as 10/14/2025 thru 12/31/2025 is 79 days in 2025 + 365 days in 2026 + 365 days in 2027 + 366 days in 2028 + 365 days in 2029 + 365 days in 2030 + 365 days in 2031 + 250 days in 2032 brings us to 9/06/2032 because the 250th day of a leap yr. is 9/06.
Could the rapture happen on the 8th & last day of the Feast of Tabernacles known as the Feast of the Ingathering when a trumpet is also blown? Yes, it could. Please read the article below which I copied and pasted from What's so significant about the shofar and its sound? | Hoshana Rabbah BlogHoshana Rabbah Blog (If you would like to read the entire article click on the link above as I only copied part of it.)
"The First Trump (or shofar blast) occurred on Shavuot at the giving of the Torah (Matan Torah) at Mount Sinai (Exod 19:16, 19). This shofar blast was of heavenly origin and is the first time the Bible records the sound of the shofar being heard." (This is also known as the Feast of Weeks or Pentecost.)"The Last Trump (or shofar blast) occurs on Yom Teruah (the Day of Trumpets/Shofar Blasts, commonly called Rosh Hoshana) is the day of the awakening blast calling the saints to prepare their spiritual garments in preparation for the coming Messiah or Bridegroom. This shofar blast corresponds to the last trumpet blast of Revelation 11:15 after which the resurrection of the righteous occurs (1 Cor 15:51–53)."
"The Great Trumpet or Final Trumpet (or shofar blast called the Shofar HaGadol) is blown on Yom Kippur (Day of Atonement) signifying the Elohim’s day of judgment and the return of Messiah Yeshua as the King and Judge of the earth. At this time, it seems likely that he will destroy Babylon the Great with its new world order religious, political and economic system (Rev 19:1–21 cp. Rev 18) just before the establishment of his millennial kingdom (Rev 20:1–10). Historically on the Day of Atonement, the jubilee trumpet sounded in Israel on the fiftieth year. At this time, the captives were set free, debts were forgiven and all land was returned to its original owners. Matthew says that Yeshua the Messiah will return with a great sound of a shofar (trumpet, Matt 24:30–31; 1 Thess 4:16). Perhaps this is a reference to the shofar ha-gadol when Yeshua returns to earth, will set the spiritual captives free from enslavement to the enslaving economic, religious and political tentacles of end time Babylon the Great."The Last Day of Sukkot 10-3-23 "The last time a trumpet call goes out for the year via the Holy Days is the last day of Sukkot. Consider the following verses regarding the two silver trumpets. Though I’m giving multiple verses for context, please take special note of the highlighted verses. Numbers 10:1-10 1 YHWH said to Moses: 2 “Make two trumpets of hammered silver, and use them for calling the community together and for having the camps set out. 3 When both are sounded, the whole community is to assemble before you at the entrance to the Tent of Meeting. 4 If only one is sounded, the leaders — the heads of the clans of Israel — are to assemble before you. 5 When a trumpet blast is sounded, the tribes camping on the east are to set out. 6 At the sounding of a second blast, the camps on the south are to set out. The blast will be the signal for setting out. 7 To gather the assembly, blow the trumpets, but not with the same signal. 8 “The sons of Aaron, the priests, are to blow the trumpets. This is to be a lasting ordinance for you and the generations to come. 9 When you go into battle in your own land against an enemy who is oppressing you, sound a blast on the trumpets. Then you will be remembered by YHWH your God and rescued from your enemies. 10 Also at your times of rejoicing — your appointed feasts and New Moon festivals — you are to sound the trumpets over your burnt offerings and fellowship offerings, and they will be a memorial for you before your God. I am YHWH your God.” They were to gather the people when both are blown. The 8th day of Sukkot is one of those days for this to happen." (Sukkot is also known as the Feast of Tabernacles or the Feast of the Ingathering.)" Leviticus 23:33-36 YHWH said to Moses, 34 “Say to the Israelites: ‘On the fifteenth day of the seventh month YHWH’s Feast of Tabernacles begins, and it lasts for seven days. 35 The first day is a sacred assembly; do no regular work. 36 For seven days present offerings made to YHWH by fire, and on the eighth day hold a sacred assembly and present an offering made to YHWH by fire. It is the closing assembly; do no regular work. So the last day of Sukkot is definitely a time that could fit for YHWH calling His people out. In fact, this is exactly what we see Yeshua doing in John chapter 7. John 7:37 On the last and greatest day of the Feast, Jesus stood and said in a loud voice, “If anyone is thirsty, let him come to me and drink. We find it interesting the verse specifically says He stood up and made this statement on the eight day of Sukkot. Could this be something hidden in plain sight? A picture, if you will, of the time He calls His bride to Him just before the judgment starts on the last and greatest day of Sukkot? So, will it happen on a future last day of Sukkot? Well, that remains to be seen. However, there seems to be yet another prophet that could be implying this very thing as well. Please consider these verses in Joel chapter 2 Joel 2:15,16 15 Blow the trumpet in Zion, declare a holy fast, call a sacred assembly. 16 Gather the people, consecrate the assembly; bring together the elders, gather the children, those nursing at the breast. Let the bridegroom leave his room and the bride her chamber. Now that you’ve read it, please allow me to offer some possibilities that we may be overlooking within it."
"Joel 2:15,16 Blow the trumpet(Day of Trumpets?) in Zion, declare a holy fast (Day of Atonement?), call a sacred assembly.(First day of Sukkot?) 16 Gather the people, consecrate the assembly; bring together the elders, gather the children, those nursing at the breast.(the seven days of Sukkot?) Let the bridegroom leave his room and the bride her chamber. (The last day of Sukkot? Day of Trumpets Blowing the Shofar Notice how it says, “Let the bridegroom leave his room and the bride her chamber.” Does that sound familiar? Let’s go to the words of Yeshua in Matthew 25. Matt. 25:6 “At midnight the cry rang out: ‘Here’s the bridegroom! Come out to meet him!’ So could the last day of Sukkot be when the bridegroom leaves his room and the bride goes out to meet Him? In light of what I see in other verses, this is something to consider."
Below is another interesting article to read as well:
The Lord required the Jews to go up to Jerusalem 3 times a year. These 3 times were the Feast of The Passover, the Feast of Weeks known as Shavuot, or Pentecost, and the Feast of Tabernacles which is also called the Feast of the Ingathering with the trumpet sounding on the 8th & last day of the Feast of Tabernacles? So will we go up to New Jerusalem on Pentecost or during the Feast of Tabernacles? This year the Jewish feast of Pentecost also called Shavuot or the Feast of Weeks begins on 6/01/2025 which is the Eve of Pentecost and 6/02/2025 is the 1st day of Pentecost until sunset begins.
