When did the three wise men arrive to give Jesus the gifts?
We don’t know for sure. Somewhere in the first 2 years of his life. It depends on how long it took them to leave to follow the star and how long it took for them to get there. Herod asked exactly when the star hadappeared, then he killed all kids two and under, trying to kill Jesus. I would assume that he put a bit of a cushion above, just in case.
