Make Baseball Opening Day a National Holiday. The Judge won't let me take my grandson out of school for that day. Help!!

A family Court Judge in New Jersey is prohibiting me (grandpa) from taking my grandson to Opening Day because school is in session. My grandson is in kindergarten. We haven't missed Opening Day since he was born. It's a family tradition. Please help. Thanks
