Q&A: Hebrew wedding tradition and 'only the Father knows the day' — Mike is curious but wants historical verification

Mike finds the Hebrew wedding tradition parallels interesting (e.g., the groom waiting for the father's release to go get the bride). But he wants to know: are these traditions actually pre-Christ or later developments? Later traditions can be read back anachronistically into Scripture. He notes that in Acts 1:6-8 Jesus no longer says he doesn't know — only that it's not for the disciples to know — so Jesus post-resurrection may now know. Mike says this is consistent with his Christology but holds it as an opinion, not a firm doctrine.
