To clarify, I meant write a program that creates an iCalendar, but
lists dates explicitly instead of using an RRULE.
While there are several iCal creators online, I don't think any of
them will handle the complexity of the rules you need, especially the
You might find an RRULE for your second condition, but I found it
easier to simply write a program.
Overall, although RRULE is a nice tool, it can't do
everything. Sometimes, you just have to specify the dates yourself,
which also gives you more flexibility to use other calendar formats
which may not support RRULE.
I've now written:
and created these blank iCalendars per your date rules above.
Be sure to check my work: make sure the dates in the calendar are
the dates you actually want.
For your first rule, I arbitrarily assumed the first event was on
February 1st. You should tweak my program to generate the correct
date (or contact me (see profile), and I can do this).
For your second rule, I created events from 2016 through 2037
To use these calendars, search/replace all instances of
with the actual summary of your event, all instances of
_DESCRIPTION_ with the description, and so on. The calendars I
created only have dates and randomly generated UIDs.
You should also change the PRODID of each calendar.
While I personally don't object, I'm not sure this question actually
belongs on webapps, since its not about an existing web application.
