creata calendar plu for mac

The key feature I use in Calendar Creator Plus that I have not found in a Mac Calendar program is to increment the age of a person every year, which prints as part of the Calendar. (Joe's 9th birthday) In the events listings you indicate a base year for any event and it calculates the value each year. I print several family calendars which automatically increases a persons age or anniversary. This is now the only program that I still need a windows based machine for. Would love to replace it so I can get ride of Windows
