According to St. Augustine the Sixth Age of the World lasts until the Second Coming of Christ. Our Lord Jesus Christ's Second Coming is, according to St. Augustine, the Seventh Day. (Ages and Days are the same. They are not of equal length.) The Eighth Day is the eternal age in the recreated universe when Christ has returned and reigns visibly forevermore.
Parallel passage references are from the full consensus of the Church Fathers according to the Council of Trent.
1 ¶ And Jesus being come out of the temple, went away. And his disciples came to shew him the buildings of the temple.
2 And he answering, said to them: Do you see all these things? Amen I say to you, there shall not be left here a stone upon a stone that shall not be destroyed.
44 And beat thee flat to the ground, and thy children who are in thee. And they shall not leave in thee a stone upon a stone: because thou hast not known the time of thy visitation. (DRV)
The temple destruction was in 70 A.D. See Luke chapter 21.
3 aAnd when he was sitting on mount Olivet, the disciples came to him privately, saying: bTell us when shall these things be? cAnd what shall be the sign of thy coming and of the consummation of the world?
[v. 3 This dates this as basically end time prophecy from this point on]
4 ¶ And Jesus answering, said to them: Take heed that no man seduce you.
8 ¶ For thus saith the Lord of hosts the God of Israel: Let not your prophets that are in the midst of you, and your diviners deceive you: and give no heed to your dreams which you dream: (DRV)
Eph:5:6, 11, 24:
6 Let no man deceive you with vain words. For because of these things cometh the anger of God upon the children of unbelief.
11 And have no fellowship with the unfruitful works of darkness: but rather reprove them.
24a Therefore as the church is subject to Christ: (DRV)
14 And the Lord said to me: The prophets prophesy falsely in my name: I sent them not, neither have I commanded them, nor have I spoken to them: they prophesy unto you a lying vision, and divination and deceit, and the seduction of their own heart. (DRV)]
5 For many will come in my name saying, I am Christ. And they will seduce many.
6 And you shall hear of wars and rumours of wars. See that ye be not troubled. For these things must come to pass: but the end is not yet.
7 For nation shall rise against nation, and kingdom against kingdom: And there shall be pestilences and famines and earthquakes in places.
8 Now all these are the beginnings of sorrows.
9 Then shall they deliver you up to be afflicted and shall put you to death: and you shall be hated by all nations for my name's sake.
10 And then shall many be scandalized and shall betray one another and shall hate one another.
11 And many false prophets shall rise and shall seduce many.
12 And because iniquity hath abounded, the charity of many shall grow cold.
13 But he that shall persevere to the end, he shall be saved.
14 And this gospel of the kingdom shall be preached in the whole world, for a testimony to all nations: and then shall the consummation come.
[This dates this from here on as the end of the eschaton. The eschaton is the consummation of this age of grace which began with Our Lord Jesus Christ’s Incarnation by the Holy Spirit, conceived and born of the Blessed Virgin Mary. The eschaton or the ending events, began with v. 3c”And what shall be the sign of thy coming and of the consummation of the world?” From here on it is the very final events leading up to Our Lord’s Second Coming.
