Best calendar app that uses icalendar files?

Anyone have a really good app for this? I just started using the Calendar extension for firefox but it is really under developed. I'd like another app that uses this standard.

What would be really cool is if there was a way to have Outlook and iCalendar on the same calendar files. My workplace uses Outlook for calendar functions, and my wife uses iCalendar to keep track of our stuff. It would be slick to have all of that off of one file.

What program does your wife use?

She uses iCal on her Mac Mini. It's a REALLY slick program. I like it a lot. I wish I could get it on my PC cry

CG! Where have you been, man?

Wow I haven't seen CG on here in a while.

My wife and I moved to the Detroit area in May. At the beginning of June, I got a new job, and it's kept me pretty busy. I've been pretty tired by the time I get home, so I don't get on much in the evenings. Now that I'm really getting the hang of things here at work, I have a few extra minutes to get back here and post during the day )

Since I don't really need to sync to anything per se, I use http//www.my.calendars.net

Yeah, I'd need something that can work with Outlook and iCal, but I doubt it's possible. Software that seamlessly integrates MS and Apple software.. unless Apple makes it, we'll never see it.

I would love it if Apple released an XP version of iCal though.. Yeah buddy!
