We don't know, sorry :/ Sometimes the chapter comes early and the break is later, and other times the opposite happens. We have no way of knowing~

And yep, but there's nothing Mashima can do about it :/ He still writes, the magazine just doesn't publish due to Japanese holidays. However, Mashima did give us two chapters in one week a little while ago, so it sort of evens out ;D
