This site is dedicated to helping those creating their own iCalendars or iCalendar feeds to ensure their calendars will work with other systems. It also serves as a meeting place for those developing validation tools to collaborate and ensure the validation is as accurate and useful as possible.
Validating your iCalendar feeds before they are deployed ensures that they will be compatible with other iCalendar systems.
A new iCalendar validator is available, based on Doug Day's DDay.iCal library. Check it out here.
For those wanting to develop a customized iCalendar feed, there are multiple free1 libraries available for development:
There are countless other commercialized implementations on the market as well, but considering the variety of free implementations, I've omitted their commercial conterparts.
This metafeed currently gathers items tagged icalvalid from del.icio.us, Technorati, Twitter, and WordPress. The idea is to gather as much related discussion and info as possible without requiring all contributors to the discussion to join and contribute directly to this wiki.
