"The Ides of Taxes are upon you!" cried the wolf to Little Red Riding Hood. "Don't be ridiculous," said Red, "April doesn't have any Ides!" Just then the tin woodsman smashed in the door with his vorpal blade and exclaimed, "Of course April has an Ides, it just happens to fall on the 13th of the month, which rather ruins the point of this whole story." THE END

p.s. - the Ides of each month of the Roman calendar were calculated by counting backwards from the calends!
