If you're looking to skip a week in the middle of your season, e.g. due to a holiday, you'll want to go into the DATES section (on the schedule maker) and push the week you want to skip back one week – all subsequent weeks will shift as well.
DO NOT try to skip a week by excluding it from all your time slots. This will result in teams getting fewer games than they should, as games for that week will be dropped.
(Some folks refer to this as a bye week. In our lingo, teams have a bye week when they sit out while others are playing (more on that here). When all teams are off, we call it an off-week.)
