Enter the Monarch and Regnal Year: Monarch:
William and Mary (William III)
years such as "1324/5" reflect Old Style dating (see note
1. Keep in mind that a monarch's last regnal
year is cut short by death or deposition and may not include all
2. Also, remember that while the so-called "Christian
year" began on January 1, the legal year began on March 25. For
example, January 1 in Elizabeth I's 1st regnal year occurred in the
Christian year1559, but legally the year was still 1558, and would be
until March 25. From January 1 to March 24, the convention is to note
both years with a slash between them, e.g. "1558/9."
3. Remember also that from 1582 onward, English
dates (Old Style) will not correspond with Continental dates.
