Well, it is my birthday and Google has announced two really cool features for the calendar program.  First is integration with the your contact's birthday field.  Google has a new calendar type called Contacts Birthdays - by selecting to display this calendar, the calendar utility goes through your contact list and displays the birthdays as a daily event (top of the day column).  Very nice and handy!  It's not as pretty as the Birthday program, nor does it have the zodiac information or age, but it's integrated in real time and you don't have to run an outside program on your data.
