I think the translation is consistent with the japanese lyrics. The "when" is indicated by ば which relates to what comes before, the ending of the festival. The arrival of a typical night is the consequence, coming after ば.

知った usually means "found out", "came to know". 知っていた would mean "knew".

The only thing that's ambiguous is whether と知った applies to just the second bit or the whole prior sentence: "I came to know that when the festival's past / The night as usual always arrives just after"
