Here's the problem with such claims:
Heaven and earth will pass away, but my words will not pass away. 36 But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only. . . 42 Watch therefore, for you do not know on what day your Lord is coming. 43 But know this, that if the householder had known in what part of the night the thief was coming, he would have watched and would not have let his house be broken into. 44 Therefore you also must be ready; for the Son of man is coming at an hour you do not expect. (Matt 24:35-36, 42-44).
