exrules

The exrules parameter takes a semicolon-separated list of quoted recurrence rule strings where each rule is an excluded recurrence of the event.

For example, the following exrules parameter specifies a recurring event that does not recur at the times specified by the two rules:

exrules="count%3D10%3Bfreq%3Ddaily";"freq%3Dweekly%3Bcount%3D4"

The first rule is for the event not to occur daily for 10 instances. The second rule is for the event not to occur weekly for 4 instances (COUNT=10;FREQ=DAILY and FREQ=WEEEKLY;COUNT=4).

The following example URL passes the example exrules parameter:
