I have updated all upcoming 2009 events on our calendar. When you post an event, scroll down beyond the message body and you will see a calendar bar. If it is not open simply click the + on the right hand side of the calendar bar. From here you can add the date to the community calendar. For multiple days, just enter the starting date and put the total days of the event in the duration section.

You can also add an event by going to the calendar, found in the options bar above and at the bottom of the calendar ADD EVENT. This will duplicate a post on the EVENTS section.
