You may review the report below and at:
https://www.rfc-editor.org/errata/eid5920

--------------------------------------
Type: Technical
Reported by: Lars Henriksen <LarsHenriksen@get2net.dk>

Section: 3.8.5.3

Original Text
-------------
Every Friday the 13th, forever:

       DTSTART;TZID=America/New_York:19970902T090000
       EXDATE;TZID=America/New_York:19970902T090000
       RRULE:FREQ=MONTHLY;BYDAY=FR;BYMONTHDAY=13

       ==> (1998 9:00 AM EST) February 13;March 13;November 13
           (1999 9:00 AM EDT) August 13
           (2000 9:00 AM EDT) October 13
           ...

Corrected Text
--------------
Every Friday the 13th, forever:

       DTSTART;TZID=America/New_York:19980213T090000
       RRULE:FREQ=MONTHLY;BYDAY=FR;BYMONTHDAY=13

       ==> (1998 9:00 AM EST) February 13;March 13;November 13
           (1999 9:00 AM EDT) August 13
           (2000 9:00 AM EDT) October 13
           ...

Notes
-----
The "DTSTART" property is not synchronized with the recurrence rule.

Although it may be removed from the recurrence set by an "EXDATE" property, the description at the start of section 3.8.5.3 leaves no doubt that the "DTSTART" property should still be synchronized with the recurrence rule.

This erratum is currently posted as "Reported". If necessary, please
