Use this property to set the reference year for the current script.
The value of the Year property is displayed in the scripts editor, on the Book Format script line, as shown on the right.
By reference year we mean a year that is used as reference for the calculation of Begin Rules/End Rules of DiaryGridLines.
For example, if you wanted to display the 12 months of the following year (ie. the year after the Year property), in a diary's back pages, then you would set the Begin Rules/End Rules as shown in the example on the right.
You can use the preferences to set a default rule or value for this property.
