It is OK to be snarky... I’m deliberating trying to let people think a bit.
I guess my point is that Jesus was the Son of God as well as the son of man. The miraculous birth of Christ is therefore every bit as important in my mind as the Resurrection. It is the fulfillment of a promise made by God. And maybe even somewhat more important because hopefully many of us will be resurrected, but there can be only one Son of God.

OK, I see what you mean.
I’ll still argue for the calendar starting with the resurrection (I’m stubborn) on the grounds that when the Christians are resurrected, there will be no further need of calendar!
