holidays have tons of parties and other things that are scheduled in the days leading up to the holiday. I am meaning things specifically you do on Christmas like open presents from Santa, Christmas dinner, or specific things you do every year on Christmas like maybe visiting your family or being with friends/neighbors, or whatever you normally always do on Christmas day...similar to the same as things you specifically do on Halloween (like trick-or-treating). Are there people that move those activities to Saturday instead when Christmas falls on Sunday?
