  To calculate the regnal year from a particular date, one subtracts the first regnal year from the calendar year in question. The year is not adjusted if the month and day falls before the regnal date, and if it falls on or after the regnal date, add one. Finally – for the regnal year of William III after Mary's death (that is, from 28 December 1694 onwards) – one also adds 6.
