Switching dates in calendar view does not skip weekends when they are disabled.

Steps to reproduce

1. Disable weekends in the calendar settings.
2. Set the calendar view to display only one day.
3. Navigate forward from Friday.

Expected behavior

The calendar should skip directly to Monday, and the date displayed between the navigation arrows should immediately update to Monday's date.

Actual behavior

The page view skips from Friday to Monday, but the date text between the navigation arrows changes to Saturday. The user has to click the arrow three more times just to get the date to advance from Monday to Tuesday.

Reproduce the issue in the calendar app with weekends disabled and a one-day view, navigating forward from Friday. Trace the single-day navigation and the date text update, then verify that both use the next enabled day and that the displayed date changes directly to Monday.
