The program runs when you switch on your PC and checks your Kith and Kin Pro database for upcoming birthdays and anniversaries of all sorts. If an event is found a window pops up to remind you about it. If no events are found the program closes down without having shown itself.
You can control which events to check for, who to ignore, how many days to look ahead and what the alert messages look like. More than one Kith and Kin Pro database can be checked.
