Was re-reading some One Piece when I noticed an interesting thing about the moon sycle.

Carrot used the power of the full moon to get a major power up couple of chapters ago and it was foreshadowed already in zou but here is the interesting part. In chapter 811 it is shown that there is a full moon, but it is hidden by the sky so thei are lucky. But therein lies the problem. From full moon to another, it takes a whole month, at least from where I'm from, but the trip from Zou to Whole Cake Island only lasted for a week or so.

So did Oda make a mistake, is the moon cycle different in the world of One Piece or is the translation wrong about the moon in chapter 811?

P.S. Did anyone else wonder about when Sanji kicked Luffy's tooth of, was the tooth still rubber even thought it was not in contact with Luffy anymore?
