With the myBirthdayReminder it is almost impossible to forget birthdays. Unless you don't use your computer often enough.
You can add a birthday to the list by pressing the New button. Enter the name, select the birthday and optionally specify an email adress. Use Edit to change an existing entry and Delete to remove it from the list.
Below the list you can choose how many days you want to be warned in advance and whether you want myBirthdayReminder to run at system startup. This way you will be notified of upcoming birthdays each time you start you computer. A list with the names will be displayed. Select a name and press the Email button to write one with your mail program.
I recommend to set the date format to MM/DD/YYYY in the country settings of the control panel.
The birthdays are saved in a file called Birthdays.txt. This file is usually placed in the Windows folder My Documents so it is saved with your usual backups. The place of the file can be changed by specifying the command line parameter folder= or by setting the registry key Folder in HKEY_CURRENT_USER\Software\mybytes.de\myBirthdayReminder.
