Turning the pages of the calendar turns up a number of other dates that play on words (or on numbers). For instance, in just two weeks, pun-loving office workers have a day of their own: September 25, or "nine-two-five." Nine days after that, on October fourth, truckers and citizens band aficionados can lean on their horns. October fourth, or "ten-four," translates from CB slang as "okay."

Six months later, March fourth, marks the only date of the year to earn a name as a call to action: "March forth!" On March tenth, men named Mario can finish their march with a rally celebrating Mario Day. Its inspiration? When you look quickly at the abbreviation for the tenth of March and say it, "Mar one-oh", it's similar to the name "Mario."

Finally, don't get fooled by the association between the first day of April and playing pranks. Retirees can also hold a special place for April first, or, as it's known to word lovers, "Four-Oh-One."
