Who says "increasing size" is more logical? Logic is something that can be applied universally, which is hardly the case here. This is more of a preference for a pattern.

So now that we discount the supposed "logic" of the British convention, "March 13, 2015" is just as unambiguous as "3 March 2015." However, the former has the benefit of being American, which both Frozen and Wikia are.
