This document defines how non-Gregorian recurrence rules can be
specified, for example Chinese New Year, in iCalendar data and with
CalDAV servers primarily by extending the RRULE property. It is a
Proposed Standard and updates RFCs 5545 (iCalendar), 6321 (xCal),
and 7265 (jCal) as indicated at the top of the title page and as
justified in the Introduction.
2. Review and Consensus
The document was augmented and improved based on the discussion on
the calsify mailing list, which the WG uses, of WG Last Call and
the Shepherd review comments. Augmentations that were made to
include extensions to xCal and jCal to handle the extended RRULE
property. A moderate number of knowledgeable people chimed in and
the document Shepherd believe review has been more than adequate.
There was significant discussion about how the SKIP property should
work, as different calendars and even different situations for the same
calendar would demand different ways of skipping invalid dates/times
and settling them onto valid ones. The result in the document represents
consensus on the least problematic way of dealing with this.
