Regnal Years in England

Most calendar systems are based on the phases of the moon and the rotation of the Earth. However, significant events were often factors in dating systems. For example, the birth of Christ divides our own calendar into B.C. (Before Christ) and A.D. (Anno Domini) (sometimes restated as B.C.E. (Before Common Era) and C.E. (Common Era). Some ancient cultures calculated their dating systems by the rule of a monarch ("In the tenth year of the reign of King ___"). This calendering system is known as "Regnal Years" (from the Latin, regnum or rule/kingdom). Regnal years were common in Asian cultures.

In England, Regnal years were not the prominent feature of the calendar system. The United Kingdom, like other European cultures, utilized the Julian Calendar until 1752 and the Gregorian Calendar until present times. However, the reigns of the British monarchs were occasionally noted and used as additional time markers. For example, Acts of Parliament used Regnal Years. Genealogists may also find Regnal Years in older English records. Below are the beginning dates for the regnal years of each of the kings and queens of England :
