Well tomorrow (today here) the 19th is also special.
On this day May 19, 1536 wife #2 of King Henry VIII, Anne Boleyn daughter of Thomas Boleyn, Earl of Wiltshire and Elizabeth Howard was executed in the Tower of London.

Think I'll wear a Kilt in memory of the poor woman.

Also, on this day in 1943, British Prime Minister Winston Churchill and U.S. President Franklin Roosevelt set a date for the cross-Channel landing that would become D-Day-May 1, 1944.

And.... Lawrence of Arabia died.

Finally: Today is Circus Day (Ringling Brothers opened 1884), Frog Jumping Jubilee Day
