No one knows the hour of the parousia or Second Coming. Only the Father knows says our Blessed Lord in the Gospel.
I think the thing to concentrate on here is that you and I will end, if the world comes with us, they are welcome. Let God's Will Be Done!
What you and I can do in the meantime is simply be ready, that is, remain in a State of Grace. Don't concern yourself about signs, wonders, the End Times, etc. If you can receive Holy Communion without committing sin, then you are just fine!
