A moon is a month, unless you're an idiot named Gillian Berrow, who defined it as a year in her G5 Bible. Needless to say, either way causes massive problems.

At least if you take G5 into account. If we're just talking about G4, there's nothing in the series that contradicts it being 30 days. Beyond the obvious problem of using it as a measure of time when it controlled by a pony who can decide what speed it moves.
