[ALUG] Online calender - any suggestions?

I am looking for an online calender for a website, largely so that I can access it from any computer wherever I am. Has anyone had a happy experience of using any such system on their sites? Google and Sourceforge reveal there are quite a few about so I thought I would fish for some recommendations before going through them all myself. While I am just after a calendering system at the moment, anythingt that offers more features than that wouldn't be a problem. I have PHP and a MySQL database to spare, so that's no problem.
