Off-Seasons allow you to create recurring event series with breaks during specific periods. For example, you can set up a recurring series of visits for mowing every Monday, while pausing from November to February, and resuming again in March.
To edit, create, and delete Off-Seasons, you can go to Settings > List Items Visibility
From here you can edit the names, edit the start and end dates, and delete the Off-Seasons entirely
Editing an Off-Season will impact the Visits associated with it. If you extend or shorten the Off-Season, you may notice changes to your scheduled Recurring Visits that rely on that Off-Season.
