The bible says nobody will know the day/year
Luke 17
20 Now when He was asked by the Pharisees when the kingdom of God would come, He answered them and said, “The kingdom of God does not come with observation; 21 nor will they say, [
f]‘See here!’ or ‘See there!’ For indeed, the kingdom of God is [
g]within you.”
22 Then He said to the disciples, “The days will come when you will desire to see one of the days of the Son of Man, and you will not see
it. 23 And they will say to you, [
h]‘Look here!’ or ‘Look there!’ Do not go after
them or follow
them. 24 For as the lightning that flashes out of one
part under heaven shines to the other
part under heaven, so also the Son of Man will be in His day. 25 But first He must suffer many things and be rejected by this generation. 26 And as it was in the days of Noah, so it will be also in the days of the Son of Man: 27 They ate, they drank, they married wives, they were given in marriage, until the day that Noah entered the ark, and the flood came and destroyed them all. 28 Likewise as it was also in the days of Lot: They ate, they drank, they bought, they sold, they planted, they built; 29 but on the day that Lot went out of Sodom it rained fire and brimstone from heaven and destroyed
them all. 30 Even so will it be in the day when the Son of Man is revealed.
31 “In that day, he who is on the housetop, and his [
i]goods
are in the house, let him not come down to take them away. And likewise the one who is in the field, let him not turn back. 32 Remember Lot’s wife. 33 Whoever seeks to save his life will lose it, and whoever loses his life will preserve it. 34 I tell you, in that night there will be two [
j]
men in one bed: the one will be taken and the other will be left. 35 Two
women will be grinding together: the one will be taken and the other left. 36 [
k]Two
men will be in the field: the one will be taken and the other left.”
37 And they answered and said to Him, “Where, Lord?”
So He said to them, “Wherever the body is, there the eagles will be gathered together.”
NKJV
And the same passage from Matthew 24
23 “Then if anyone says to you, ‘Look, here
is the Christ!’ or ‘There!’ do not believe
it. 24 For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect. 25 See, I have told you beforehand.
26 “Therefore if they say to you, ‘Look, He is in the desert!’ do not go out;
or ‘Look,
He is in the inner rooms!’ do not believe
it. 27 For as the lightning comes from the east and flashes to the west, so also will the coming of the Son of Man be. 28 For wherever the carcass is, there the eagles will be gathered together.
The Coming of the Son of Man
29 “Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of the heavens will be shaken. 30 Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory. 31 And He will send His angels with a great sound of a trumpet, and they will gather together His [
d]elect from the four winds, from one end of heaven to the other.
The Parable of the Fig Tree
32 “Now learn this parable from the fig tree: When its branch has already become tender and puts forth leaves, you know that summer
is near. 33 So you also, when you see all these things, know that [
e]it is near—at the doors! 34 Assuredly, I say to you, this generation will by no means pass away till all these things take place. 35 Heaven and earth will pass away, but My words will by no means pass away.
No One Knows the Day or Hour
36 “But of that day and hour no one knows, not even the angels of [
f]heaven, but My Father only. 37 But as the days of Noah
were, so also will the coming of the Son of Man be. 38 For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, 39 and did not know until the flood came and took them all away, so also will the coming of the Son of Man be. 40 Then two
men will be in the field: one will be taken and the other left. 41 Two
women will be grinding at the mill: one will be taken and the other left. 42 Watch therefore, for you do not know what [
g]hour your Lord is coming. 43 But know this, that if the master of the house had known what [
h]hour the thief would come, he would have watched and not allowed his house to be broken into. 44 Therefore you also be ready, for the Son of Man is coming at an hour you do not expect.
NKJV
Jesus uses the word hour, but that can't be literal, more like he means semester or even decade. I think now that Jesus is glorified, that He has all knowledge.
I made this thread regarding where they are taken, here:
Two in a bed one taken... where? Where there is a dead body, the vultures will gather. This means?
And:
One Shall Be Taken, One Shall Be Left Grinding.
