The monthly calendar template creates a Gregorian calendar for monthly-based reports that can be used with the Month-related calculations.
The following are the global variables that can be customized in the DefaultVariables setting of the template configuration. All the global variables are defined as strings in the JSON configuration, even when the content is a number.
__FirstFiscalMonth
Month number (1-12) of the first fiscal month of the year.
__MonthsInYear
Number of months in one year. It must be 12 when the template generates a Date table. In future versions of the template that generate one row for each month without using a Date column, this number could be 13 to support accounting calendars that have an additional month for adjusting journal entry transactions.
