You guys can have it as it right now. The birthday hack isn't going to change and calendar.php is a stand alone file so it is nothing to use it right now with birthdays. When I get the next version done sometime this week you can just dl the new calendar.php and the upgrade.php that will create the new table to hold the user events.
Just download the birthday hack in this same forum and dl
Calendar.txt and rename it to calendar.php. Make a link to calendar.php and away you go. The templates you need to make are listed at the top of calendar.txt
(if you click the link and see screwy code just view the source and copy/save it to calendar.php)
