I share custody of my son with my ex. He gets him three weekends out of every month. The 2nd, 3rd and 4th. I have him on the 1st weekend. The judge said that our weekends start Friday at 6:00 p.m. and end Sunday at 9:00 p.m.. This month I planned a trip to the snow on my only weekend with my son. Since the 1st is on a Saturday this month, I thought that my weekend was next week, when I could finally get a full weekend with him. Is this the case or is this weekend mine even though the first of January is a Saturday?
