I don't think this library parses RRULE:FREQ=YEARLY;INTERVAL=1;COUNT=6;BYMONTH=2;BYDAY=3MO
(president's day)
correctly. I tried it, and it gives me back
RRULE:FREQ=YEARLY;INTERVAL=1;WKST=MO;DTSTART=20190103T054718Z;COUNT=6;BYMONTH=2
which is incorrect. I think the issue is the BYDAY not parsing, but that's just a guess.
