The intervals examples focus on the lower-level time-grid pieces used by QCalendarDay. They show how interval sizing, navigation, and month-style helper views can be combined when the default day or week examples are not quite specific enough.
Use these recipes when you are building custom scheduling controls around the interval grid, especially when the calendar needs to coordinate with an external month selector or custom navigation UI.

Calendar Adapters
Interval views keep time-of-day labels calendar-neutral. Use Timestamp calendar adapters in interval and header slots when the interval surface needs native calendar context.
