** Default Calendar is the only calendar on the Select Calendar list. Are OldStyle and Simple also templates? **
Yes.
** If yes, why don't they show on the list? **
Because they are templates not calendars. The Select Calendar screen is for selecting calendars not templates.
** How do I add templates to the Select Calendar list? **
You can't AFAIK. If you want to change the template the calendar is using, you do so from the Calendar or Template Options administration screen (i forget which). It is not a choice regular calendar uses get to make.
