Use the Offset from Script Year mini-calendar modifier to base the reference year of a mini-calendar on the year of the script (in fact meaning that the mini-calendars will each be displaying the same date for all pages and dates of the diary).
:year+YY or :year-YY
where YY represents the numerical offset running from 1 to 99.
➢The current script year can be specified with the modifier :year+0 but it can also be specified more simply as :year where the +0 is omitted.

The offset from script year modifier is useful when a grid runs over more than one year, but we always want the exact same months to appear on each page (ie. a change of date of the current page does not change the year or months displayed by the mini-calendars).
