I am making a site where people can log routine important dates/events. These dates are specific to them and I would like them to be displayed on a calendar and agenda form. Most calendars I have seen want a single set of data set (e.g. for bookings) but I am looking for user specific calendar which can pull relevant (and user specifc) data from a data base (user entered information).
Advice on tools / how to do this would be greatly appreciated!
