Yes, you count days for everything that’s 60 days (used to be 180 days to book dining, or 120 days to book something I can’t remember what, and that was really confusing to calculate), because it’s so many days in advance. I thought you wanted the DVC booking window that’s based on months, not on days, to somehow vary depending on whether a month had 31 days or not, due to your confusion about being able to book a DVC reservation for November 30 on December 30 but not being able to book a DVC reservation for December 1 on the day after December 30.
