Check with the clerk ,but be sure where you are actually suppose to appear .
Some smaller communities hold court on weekends .
Judging from his name, I'm guessing he's from Brooklyn, in which case, I
think the date gets pushed to the next day in which the court is open (i.e. the following Monday). I'd still call and check though, as sometimes they may assign a completely new date.

They are definitely not dismissed
