Enter the month and year: Month: (January=1) Day:

Enter the Monarch and Regnal Year: Monarch: Regnal Year:

* Double years such as "1324/5" reflect Old Style dating (see note below).


1. Keep in mind that a monarch's last regnal year is cut short by death or deposition and may not include all dates.

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.
