We can be certain that the most important events of Jesus’ second coming will fall on the “Feasts of the Lord” as listed in Leviticus 23. Feasts of the Lord (or MO’EDIM in the Hebrew, KAIRON in the Greek). These were instituted by God, and given to Moses and the Israelites (Lev. 23) prior to their entering the Promised Land, and they played prominent roles in the Tabernacle and later in the Temple services.

God established these “appointed times” as “rehearsals” of the great redemptive events in Jesus’s life. The celebration and symbolism of each “Feast” foretold the redemptive event. These Feasts are divided into four “spring” Feasts during the spring of the year and three “fall” Feasts during September and October.
The primary prophetic meanings of the “spring” Feasts have already been fulfilled by Jesus at His First Coming.
Most Christians are familiar with Passover, the first of the four spring Feasts, and how it prefigured the death of Jesus on the cross. The blood of the sacrificial lamb, which was spread on the Jewish doorframes in Egypt to protect them from the Angel of Death, foreshadowed the blood of Jesus, the sinless Lamb of God. As we know, Jesus was the perfect, sinless, blood sacrifice uniquely acceptable to God. Only his death could pay the substitutionary judgment required by the Holy God for atonement of the sins of those who put their trust in him. Only Jesus, being the sinless Son of God, was forever acceptable as the sacrifice to take upon himself God’s punishment for our sins—-in God’s eyes our sins were transferred onto Jesus, and his death, and his death alone, paid our sin-debt before God. This is all pictured in Passover and is the primary and initial step in God’s plan of redemption. The three other spring Feasts prefigured the other redemptive works of Jesus at his First Coming. The second Feast, the Feast of Unleavened Bread, foretold the burial of Jesus, and the third Feast, First Fruits foretold the resurrection of our Lord. Shavuot (Pentecost) foretold the coming of the Holy Spirit and the birth of the Church. In addition, there are three Feasts of the Lord that have not yet been fulfilled, the “fall” Feasts—-Yom Teruah (Feast of the Blowing of Trumpets), Yom Kippur (Day of Atonement), and Sukkot (Feast of Tabernacles). All of these fall Feasts occur in September/October on our Gregorian calendar and occur in the seventh month, Tishri, on the Jewish calendar each year. All these will be fulfilled related to Jesus’ Second Coming.
The Day of the Lord (God’s Wrath on the earth) begins on the same day as the Rapture. It extends from Yom Teruah on our Gregorian calendar (Tishri 1 on the Jewish calendar) of the Sixth Year of the 70th Week until Yom Kippur at the end of Year Seven.
The Resurrection and Rapture will occur on Yom Teruah at the end of the Sixth Year of the 70th Week, and Jesus will physically land upon the earth in power and glory on Yom Kippur at the end of Year Seven. That period is one year and ten days. This is supported by the witness of Isaiah: “For the Lord has a day of vengeance, a year of recompense for the cause of Zion” (Isaiah 34:8). The ten days between Yom Teruah and Yom Kippur are known as the Days of Awe. These are ten days of introspection and repentance for Israel as they prepare for the Day of Atonement (Yom Kippur). We have seen that Daniel and his friends were tested for ten days when they didn’t eat the King’s food. We are also told in Revelation that the believers in Smyrna will be imprisoned for ten days as well. Both of these are allusions to this time of repentance. It is incredibly likely that the seven Bowl Judgments will happen during these ten days during Year Seven, immediately before the end of the 70th Week. Interestingly, Noah was in the Ark for exactly one year and ten days (calculated from Gen 7:11, Gen. 8:14). This is not a coincidence. Also, the year before a Jubilee year is always one year and ten days.
In the Olivet Discourse Jesus told us the Rapture of the Church will be “like the ‘days’ of Noah.” The Church will be off the earth in Heaven for the identical time that Noah was raised above the earth on the Ark: one year and ten days.
