Here’s a few calendar/event sites you should check out.

Upcoming – The one that Yahoo! acquired. Good, but suprisingly lacking in features when it comes to listing public and private events.

30Boxes – A surprisingly good looking calendar. This would be great for personal use, and things you’d like to share with the world. This might be good until Google Calendar comes out.

Eventful – The most feature filled calendar site. It searches for events automatically, along with posted ones. You can create your own calendars, groups, venues, etc. Create automatic events (weekly, daily, etc.) It also has several privacy features, for members, and non-members. You decide what to share. You can also place calendars, venues, and anything else on your website or blog.

So theres that. Check them out, and pray Google Calendar will come soon.
