I tried that using -10 as the start date and then with 2009 but the date picker range is still 2013 to 2028. The default was set to -3 so that start date should have been 2015 not 2013. This occurs in the date picker in a new post and in editing a post. Any suggestions? Docs indicate that the date picker is associated with the JQuery UI. Could the date rage be set in that feature?
