Javascript library to generate iCal format?

Does anyone kn开发者_如何学运维ow if there is any JavaScript libraries that generates iCal format? (RFC 5545 or RFC 2445 standard)

It would be good if it also provides user interface for it. Something similar to OWA Repetition window or Google Calendar repeat popup.

Thank you.

I haven't tried this myself but this looks like it will work jQuery iCalendar.
