The Anniversary content plugin is a simple plugin designed to display the right number automatically for anniversary style displays. Useful for displaying items like age or similar items that change every year on a given date. The plugin uses the format {anniversary YYYY-MM-DD} to designate what year, month and day the anniversary is on and replace this with the appropriate number.

There is a Joomla! 1.5 version and a Joomla! 1.0 version available.
