No founder, establishing act, or first observance has been documented for National Robert Day. It circulates as an unofficial April 6 observance across independent holiday calendars.
When Robert meant robber
Within two centuries a name built to mean bright fame had a second life as an insult. The Middle English Dictionary records Robert as a designation for a robber, a vagabond, or a lowly person.
English law took the word up directly. A statute of 1331 complained of robberies and felonies committed by men called Roberdesmen, Wastours and Draghlacche. A further statute in 1383 ordered that the earlier one be kept.
