How to display different calendar views?

please tell me how to turn on week, month, listviet display modes on upcoming page

the op posted instructions

not sure i understand? there are clickable functions on the calendar interface? what do you mean by externally?

I have read but can’t figure out how to configure to display at font-end (user interface)

click the arrow buttons at top left corner of calendar, or the view buttons at top right corner of it. are you looking for a button to make the calendar?

the instructions above show how to insert it with bb code. no buttons needed. the entries are created from subsequent replies with date formatted entries from the insert date/time button on the comment box formatting toolbar.
