What is actually better about it? It’s a bit more intuitive except for where it isn’t, and it forces people to develop an entirely new concept of the 0th of January (and occasionally 0th of June). What do we do on the 0th? How does that fit into things that cycle with a period of 1 month? It breaks the idea that a 1 month period is equivalent to a 4 week period, which is supposed to be the entirety of why we’re doing this in the first place.
