In case you're wondering why President's Day (or any other holiday, for that matter) shows up in Outlook for previous years, but not for 2008, I'll let one of Outlook's program managers explain:
It's nice to finally have some of these holidays back without having to go in and manually add them. If you happen to be interested in manually adding some holidays (birthdays, special events, etc.), the blog entry above mentions a cool way to edit the "holiday file" to include anything you want.
When we shipped Outlook 2003, we only included holiday information through the end of 2007. Since it's now 2008, you're probably wondering how you can get holidays back on your calendar again. An update is now available to fix this issue by downloading and installing a patch for Outlook 2003. More information is available through http://support.microsoft.com/kb/924423
This update will replace the holiday file (Outlook.hol) with the latest holiday information, and you can use the same process from above to add holidays for 2008 and beyond into your calendar.
