Convert English Regnal Years to Calendar Years

  In early English legal documents, the year is often given as the number of years in a particular monarch's reign.  For example, Charles I acceded to the throne on 27th March 1625 so his first 'Regnal Year' ran from 27th March 1625 to 26 March 1626.  So 3rd June 1633 might appear as '3rd June 9 Charles I' meaning the 3rd June in the 9th year of his reign.  Apart from Henry II, Richard I and Henry III, a monarch's reign was considered to begin when the previous monarch died, abdicated or was deposed  -  the Coronation date is always a little later. Two calendar years given are the Old Style/New Style calendars more information.  The dates given for a monarch's reign are all in the present Gregorian calendar.
