Over the years I've managed to committ a lot of important historical dates to memory. I could tell you the birth dates of some of England's monarchs, the execution dates of other monarchs, and the dates of important events in the United States.
Just a few I know from memory:
Queen Elizabeth I was born on September 7th, 1533.
Anne Boleyn, Queen Elizabeth's mother, was executed at the Tower of London on May 19th, 1536.
Queen Elizabeth I died on March 24th, 1603.
Queen Marie Antoinette of France was executed by the guillotine on October 16th, 1793.
Queen Victoria, who was born in 1819, ruled England from 1837 until 1901.
In the United States, the Stock Market crashed on October 24th, 1929.
The Japanese bombed Pearl Harbor on December 7th, 1941.
