The Day Planner comes with a set of default Sections that break your day into morning, afternoon, etc. But, we know these won’t work for everyone. The Planner Template Chooser can be opened from the button at the top of the Day Planner.
This will let you choose from some built-in Planner Templates or from a catalog of Templates that we are constantly updating. See: How to use Planner Templates and the Planner Template Chooser?
Note that the Planner Template Chooser is only currently available on Windows and macOS. On iOS, for now, you will need to manually edit Sections. See: How do I edit, add, delete, and reorder Sections in the Day Planner?
