Weekly recurring events in iCalendar

问题

I have pasted below my ics file for a recurring event, It is a weekly recurring event, this recurs on monday, tuesday, wednesday. I checked the syntax, It seems to be fine. Is there anything wrong in this.

What have you done to assess whether something is wrong? What errors have you experienced?

Did you validate it ? http://severinghaus.org/projects/icv/

have you tried to load into any ical clients (google calendar,outllok, thunderbird etc) - what do they do?

Have you checked against the spec for examples:

http://www.rfc-editor.org/rfc/rfc5545.txt has examples like this RRULE:FREQ=YEARLY;BYMONTH=4;BYDAY=-1SU;UNTIL=19730429T070000Z

Possibly the weekly should follow the RRULE immediately your exrule should be superfluous if BYDAY is there.
