Calendar recurrence

in the calendar we have recurrence every day, week, month, year… I need to place something every 5 days for a few months.
I found it impossible.
Is it because it is really not possible or because I did not know how to?

When defining the event, go to the Recurrence tab, select Daily, and then select every 5 days under Pattern. You can then define a range to end after a certain number of occurrences, or by a certain date.


Thank you very much.
It is so simple!
