In conjunction with our report on the Little League age changes, and which leagues it effects, below are Little League age charts, calculators, links to division rules and a conversation on cutoff dates. Do note, although Little League is its own organization, at least a few other youth baseball leagues follow their lead on rule implementations. Other leagues do not follow them at all---which makes understanding the rules before you sign up both vitally important and difficult to keep track.

*The 12U 2018 season is the last year and age class (2005 Birthdays) that will allow the May 1st birthday ball players. Come 2018 and beyond all leagues and ages will use September 1st.

Little League Age Charts

Below are the age charts for the 2018 and 2019 seasons.
The major hullabaloo that sent many to the internet scrambling for answers was the change in the cutoff date for Little League international. We discuss the reasons and history behind that here.
