The dates can be deleted and edited from the program. There is no need for the BDE from Borland; this would be really a bit overkill.
The main screen from the program is very simple. As can been seen, also for Christmas you need to enter a date in the past, or at least in the current year.
All dates are save in a (ASCII) file, one line for each date, like:
Christmas * 25/12/1999.
The strong point of this program is that it works the same on computers with a different Windows date format setting.
