Thank you for your question.
Jesus said that no one would know when he was going to return:-
Matthew 24:35-36 Heaven and earth shall pass away, but my words shall not pass away. But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only
Rather the focus of Scripture is that because Jesus is going to return we ought to repent
Acts 3: 19-21 Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord; And he shall send Jesus Christ, which before was preached unto you: Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.
The reality of the situation is that none of us know when we will die. As death is a dreamless sleep until the resurrection when we die the next thing we will know will be the resurrection at the return of Jesus so how long it will be until Jesus returns is not really that important to us as individuals. What is important is whether we have formed an association with God and His son Jesus.
I hope this helps
