TermineX uses the Gauss-algorithm for the Easter calculation (valid for all years after 1582). It is able to calculate all essential German, Bavarian, Austrian and Luxembourg holidays and also some French holidays. Use the Preferences-dialog to enable/disable the holidays you will need. In this dialog you can also determine the preview/look-back period and the language of the user interface (German, English, French). Via "File / Enter new birthdays..." you can define your own "special days / birthdays". The calssical holidays will be displayed in the left section of the program's main window, and the user defined "birthdays" will be displayed in the right section of this window. In case of "birthdays" the entered birthday-date will be displayed.
"File / Calendar..." will show the actual year's calendar. Sundays and holidays are displayed in red. Actual day will will be highligthed in blue. Help tags will be displayed when the cursor will be placed on a holiday date, showing the name of the holiday (MacOS-X only). You can change the calendar's year via the disclosure triangle in the window’s upper right corner: an edit field will appear where you can enter the year (or use the up/down arrows (down to 1582 and up to eternity)).
