This series of errors are likely caused by one or more improperly formatted birthdays in the birthday field on the people screen. Birthdays formatted like the examples below could cause these errors:

00/01/2008

01/12/

12-12

In these cases, the computer does not know how to interpret the date you have entered. In practice, it is best to not include a date when you are unsure of the year or month. You should always format the birthday like this:

01/12/2008

If you do not want the year to show on reports and printouts, you can use the utilities menu's settings window to hide the year.
