But the word already means that the both decision and planning were in place before the blessed event. I still don't see how the presence or absence of at would change that.

Sep 4, 2016 at 23:27	comment	added	deadrat		I'm sorry, but I can't understand your explanation. You say that the day of execution was not decided at the time of birth, but that's exactly what the sentence says. Not just decided, but planned. Whether this is done by a literal person or metaphorically by the "larger system" would seem to have no effect on the syntax. the moment X is an idiomatic adverbial of time that doesn't need a preposition, like tomorrow, but unlike tomorrow can take one. Thus planned the moment you were born is as unremarkable as *planned at the moment you were born. They mean the same thing.
