Good question @jfloyd33. It is true that the Father, Son and Holy Spirit are co-equal in all of the attributes of God, including omnipotence, omniscience, omnipresence and so on.
However, when Jesus entered this world, Philippians 2:5-9 describes how He voluntarily did not use His divine attributes. Hebrews 2:9 says that He was made temporarily lower than the angels. The reason for this was because one of His purposes in coming to earth was to demonstrate to the rest of us how we should live - to be an example for us to follow (I Peter 2:21).
Well, obviously we don’t have all the “omni-” attributes of God, so if we’re supposed to follow His lead, then He would have to do life as a man - handicap Himself in a way that we could follow.
So He made Himself just as limited in power and wisdom and so forth as any mortal would be. He performed no miracles, He preached no sermons, He displayed no supernatural wisdom that any other mortal could not have displayed - until after His baptism when the Spirit anointed Him. And from that time forth, He began doing all of His mighty works in the wisdom and power of the Spirit, at the direction of the Father - just as He tells His followers to do.
So if He didn’t know the day or hour of His return, it was only because the Spirit did not reveal it to Him. If He did supernaturally know what His enemies were thinking on various occasions, it was only because the Spirit did reveal it to Him. And He said that the works He did, His followers could do also, and even greater works than these.
But the night before His crucifixion, in John 17:5, He prayed for His Father to glorify Him with the glory which I had with thee before the world was. At His resurrection, He began once again using all of His divine powers, not as the Spirit filled Son of man, but as the Son of God Himself. I’m pretty confident that He knew then the time of His return. But when His disciples, asked Him one last time before He ascended to heaven, He still told them it wasn’t for them to know the times or seasons - Acts 1:7.
I hope this helps you to make sense of this.
