You might consider using MySQL's date functions. The MySQL date
type will handle dates between 0 and 9999 (Y10K bug alert!).

MySQL also has date_format and str_to_date.

I am not sure what calendar is used for datediff(), as gaps in
the calendar and other strangeness like variations in the beginning
day of the year will also affect the results.
