age based teams by calendar year makes sense. clubs are planning on going to grade based down to 4th grade so they can field more teams, make more money. should not be a concern to them to do it by calendar year d.o.b. for same. $$$ is still more and it is fair to the kids.
I don't understand your logic - most clubs already have two teams per age (typically older/younger) so how does going grade based change anything?
