Happy Birthday, Mr. Washington!
In A Small Tangent...The British Empire used the Julian calendar until 1752 when it switched to the Gregorian calendar. Created in 46 B.C. by Julius Caesar, this calendar contains the same basic structure as the Gregorian calendar with two major differences:
The new year begins on March 1st instead of January 1st.
It has a simple but inaccurate system for dealing with the extra bit of time accumulated each year.The result is that George Washington was born on February 11, 1731 in the Julian calendar. But February went from the last month of the year to the second month of the next year, George's birth year changed from 1731 to 1732, while the day changed from the 11th to the 22nd.
