Acts 1:7

Verse 7. It is not for you to know. The question of the apostles respected the time of the restoration; it was not whether he would do it. Accordingly, his answer meets precisely their inquiry; and he tells them in general that the time of the great events of God's kingdom was not to be understood by them. A similar question they had asked in Mt 24:3, "Tell us when shall these things be?" Jesus answered them then by showing them certain signs which should precede his coming, and by saying, (Mt 24:36) "But of that day and that hour knoweth no man, no, not the angels of heaven, but my Father only." God has uniformly reproved a vain curiosity on such points, 1 Th 5:1,2; 2 Pe 3:10; Lu 12:39,40.
