Little League Baseball® to Begin Utilization of August 31 Age Determination Date for the 2018 Season; Children Born Between May 1 and August 31, 2005 to be Grandfathered as 12-Year-Olds For 2018 Season http://www.littleleague.org/media/l...ember-December/llb-age-determination-date.htm I missed this when it came out in November - just noticed it when our LL sent out a registration notice for this spring. This is a big deal. There must have been TONS of complaints about the changes last season. This gives my November b-day 8 year old who was baseball 8 last year, another year at baseball 8 - an extra year in LL - which I'm only considering an extra year because last year's change took a year away from him. I think this is a good move by LL, the change last year wasn't very well thought out.
