Went to the user guide and found the solution. For the Series 4, 5 it works differently. On the today view without he < press down and hold until a selection for the view comes up.
From the documentation:
While you’re viewing events in the Calendar app on your Apple Watch, you can switch between views by pressing firmly, then tapping an option:
- Up Next: Shows your upcoming events for the week.
- List: Shows all your events from yesterday through six days from today.
- Today: Shows just the events for this day.
To see the whole month, tap < in the top-left corner of any daily calendar. Tap the monthly calendar to return to Today view.
To see another day, swipe left or right if you’re in Today view; if you’re in List view or Up Next view, turn the Digital Crown.
To jump back to the current day and time, firmly press the display, then tap Today.
Once you make the selection it will default to this for future selections.
Hope this helps someone else.
Thanks
