“No one knows the day or hour when these things will happen, not even the angels in heaven or the Son himself. Only the Father knows.” Matthew 24:36

That being said…

“There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexity at the roaring and tossing of the sea. People will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken. At that time they will see the Son of Man coming in a cloud with power and great glory. When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near.” Luke 21:25-28
