Well. May Day is not Mayday, the internationally recognized radio word to signal distress. It is used mostly by aircraft and boats. How many times do we hear Mayday! Mayday! Mayday! on a TV show or movie.
Mayday first came to be in 1923. There was a lot of traffic between England and France in those days, and there were enough traffic (and disaster) problems over the English Channel that a good distress signal was needed. One that everyone could easily use and understand. And, there were some problems with using S.O.S. for the radio (voice) such as:
Mayday was the phonetic equivalent of "M'aidez", the French for "Help me."
So, there was an RAF "flying boat" whose engines failed over the Channel. And the pilot shouted out M'aidez M'aidez M'aidez over the radio and that was it. It stuck. M'aidez becomes Mayday. In 1927 the United States formally adopted Mayday as an official radiotelegraph distress signal.
OK, Tom, land the plane.........
Today is SUNDAY ("sun's day") and tomorrow is MONDAY ("the moon's day") and May Day is an ancient festival marking the first day of summer. International Workers' Day took over "May Day" but it is very different from the traditional May Day.
So, on this SUNDAY we celebrate May Day and tomorrow will be MONDAY, where hopefully while at work - you do not feel the need to shout out Mayday! Mayday! Mayday!
Now you must excuse me, I need to get ready to dance around the maypole.
