Additional info

According to the RFC specification https://www.ietf.org/rfc/rfc2445.txt and the wording in the app (on date) the event should end on the day set.

RFC:
The UNTIL rule part defines a date-time value which bounds the
recurrence rule in an inclusive manner. If the value specified by
UNTIL is synchronized with the specified recurrence, this date or
date-time becomes the last instance of the recurrence. If specified
as a date-time value, then it MUST be specified in an UTC time
format. If not present, and the COUNT rule part is also not present,
the RRULE is considered to repeat forever.

Reproduce the daily event recurrence in the Calendar app using a Monday start and Friday end date. Trace how the RRULE UNTIL value is handled, then verify that the recurrence includes the selected Friday as required by the cited RFC.
