Let me ask you a question about events on multiple days.
For example, an event takes place once a week on Tuesday for 5 weeks. Thus we have 5 dates for an event. In the calendar, if you enter the start and end date, all days between the first and last date are marked.
Therefore, the question whether it is possible that only the 5 Tuesdays are displayed for this event, without the same 5 weeks are blocked in the calendar.
