Description
I have an event created with Apple Calendar on a CalDAV server with this RRULE:
RRULE:FREQ=YEARLY;UNTIL=20230430;BYMONTH=4;BYDAY=SU,SA;BYSETPOS=-1
When syncing this to another CalDAV server, I get this error message:
`<s:message>This recurrence rule does not generate any valid instances</s:message>

Research direction
Start by tracing how vdirsyncer processes the reported RRULE during calendar synchronization; the issue does not name a file, test, or entry point. Reproduce the sync with the supplied rule and compare the generated instances with the server response. Done means the rule is handled correctly or the invalid-rule behavior is clearly documented and covered by a regression test.
