This setting is used to define the Week Numbers that are shown in the six-monthly and monthly Calendar views. Week Numbers can vary from country to country and depending on when the year started.

Click the [Settings] button in the Master Control panel or select 'Settings' from the File menu to open the 'Settings' list. Double-click 'Weeks' in the list. The 'Weeks: Browse' window lists the records that have already been entered: double-click one to modify it or click [New] to create a new record.

Complete the grid for each year of use as shown in the illustration (there is no need to have the years in order, but you should only enter each year once). Click [Save] in the Button Bar to save, and then click the close box to save the record.
