[Not gonna take it anymore]

Should have added:

If Jesus himself said that no one knows but the Father, who am I to say I do know? Or who is anybody else?

[GiovannaNicoletta]

But Jesus also said that those who know Him as Savior would know when His return for His bride was near, even at the door.

So apparently, Jesus believes that those in Him would know not the exact time of His return, but based on the signs that He gave for the Tribulation coming to pass, which are happening now, we would know that His return for His Church is very near.

And, Jesus also commands us to watch for His return. So it is possible to know when the Rapture, which is a signless event, is very close to occurring.
