Dusty Linden over at the Second Life Blog has posted an event list on their blog. I'll just post the short version here, you can use the Second life blog Link to get the rest of the story.

Tomorrow— June 23, 2009— marks 6 FULL years of Second Life. To celebrate 6, and our passage into year 7, your fellow Residents have been busy for months, planning a 20-Region party around the theme "The Future of Virtual Worlds". Come by tomorrow after 10 am SLT, as they turn on the lights and throw open the doors. Philip Linden will start the event at 10 with a talk at the main stage. And the exhibitors have a lot to show you. See what they think the future will be like! They've created a burned-up meteor called Dallier's Hope with hundreds of exhibits awaiting your exploration, from the hilarious to the deeply thought-provoking. http://tr.im/SL6Bexhibits
