The Feasts of the Lord are God’s prophetic calendar for Jesus’ first and second coming to Earth. The Spring Feasts predicted His first coming so it is reasonable to assume the Fall Feasts will predict His second coming.
The Rapture will likely occur on Yom Teruah of the Sixth Year of Daniel’s 70th Week and the physical Second Coming will likely occur on Yom Kippur of the Seventh Year at the end of Daniel’s 70th Week. The Resurrection and Rapture (which occur at the trumpet blast of the Seventh Seal) will occur on Yom Teruah (The Feast of Trumpets).

Is there any Biblical support for other Feast Day fulfillments? Interestingly, there is! The Sixth Seal is the Celestial Earthly Disturbance Event. Based on our Feasts model, we predict it will be fulfilled on Shavuot (Pentecost). The initial primary fulfilment of Shavuot occurred when the Holy Spirit came upon the disciples in Jerusalem, and they spoke in other languages to the listeners in Jerusalem. Peter delivered the famous sermon found in Acts 2 to those listeners, and 3000 people were saved and baptized. In that sermon, Peter quoted Joel 2:30-31 which directly references the Celestial Earthly Disturbance Event! Peter openly linked the Celestial Earthly Disturbance Event with Shavuot (Pentecost) and with the later Rapture/start of the Day of the Lord (on Yom Teruah). linking the ultimate fulfilment of Shavuot (Pentecost, the day on which Peter was speaking) with the ultimate darkening of the sun and moon as part of the future Celestial Earthly Disturbance Event at the Sixth Seal (Joel 2:31 and Rev. 6:12)—-and also linking the Rapture/start of the Day of the Lord on Yom Teruah (the Feast of Trumpets), to follow shortly after that time (Yom Teruah occurs about four months after Pentecost). This is extremely strong evidence that this Sixth Seal will open on Shavuot (Pentecost), and by extension, from other correlations we have already noted, that all the seals will be fulfilled on the sequential Feasts’ dates. This is speculation, but a logical case is being built for this to happen as such. As you can see, knowing the Hebrew roots of our Christian faith is important in correctly interpreting much of scripture.
