We are told Jesus grew in wisdom while He was growing and incarnated, revealing there were likely some limitations on the knowledge He had at the time. At the beginning of the book of Revelation, we are told the Father gave Jesus a revelation for Him to share with His servants. We don't know exactly when this additional information was given to Jesus, but we have a decent idea when He chose to pass it off to us through John. There's no reason at this point to assume Jesus is still without that information.
That said, those verses are very Jewish in context. The day no one knows the day or the hour would have brought to mind the Feast of Trumpets, as it is another name for that feast. Similarly, here in America, if I were to mention 'turkey day', people would know it as an idiom for Thanksgiving. And saying only the Father knows alludes to their wedding ceremony preparations. Typically, the groom would go to prepare a place for his bride at the Father's estate, and when the Father was satisfied with the preparations, he would then tell the son to go get his bride. This tradition also plays into the understanding of when Jesus told us He was going away to prepare a place for us, and then come back and receive us unto Himself. In the context of this wedding tradition, only the father of the groom knew when the son would be returning for the bride.
As for the timing of the rapture. Paul spends a great deal of time in explaining and reinforcing that Jesus is the head of the Church and we are all members of His body. Corporately, we all are a part of a singular entity. He also tells us the rapture will take place at the 'last trump', which again is in reference to the Feast of Trumpets where the last trump is in reference to last of a series of 100 trumpet blasts.
I happen to be one that when I look at the identity of the manchild raptured in Revelation 12, it looks just like the rapture of the Church. The manchild is identified as the one who will rule the nations with a rod of iron. So, when one looks at who rules with a rod of iron, Psalms tells us it is Jesus who had that rod. However, Revelation 2 further expands on that and Jesus tells us that rod is further given to the Church. So, the manchild describes characteristics of both Jesus and His Church. And since the Church and Jesus are all one body, when He returns for us, both living and dead, we will all be together for the first time as the manchild with the rod of iron to rule the nations.
It just so happens that sign of the birth and rapture of this manchild found in Revelation 12, takes place in the heavens this year on the Feast of Trumpets, 132 days from now. Make of that whatever you will.
