If you do not see the "Today" button displayed under the search field, then you may want to try refreshing the iCal plist file.
You will find the com.apple.iCal.plist file in your Macintosh HD/Users/yourusername/Library/Preferences Folder. To get to the Library folder use Finder>Go>Depress the "Option" Key and select LIbrary. Quit iCal, drag the .plist file to your Desktop. Then log out/in or restart.IMac 24, Mac OS X (10.7), iPad 3G, iPhone 4, 20GB iPod Color, iPod shuffle
