Does the distress call "mayday" have anything to do with the May Day holiday?
Maybe the original person in distress needed the help of a May pole to save him? Just spitballing here.
Your theory, though intriguing, is very incorrect, I am sorry to say. The two terms don't have anything to do with each other. "Mayday" was coined in 1923 by Frederick Mockford, an airport radio officer in London. It sounds like a French term for "come and help me," which is why he went with it. May Day the holiday, however, has roots in ancient Celtic and Roman festivals welcoming the arrival of spring.
It does not. "Mayday" is a distress call. May Day is a holiday where people go into Seattle and protest about the stuff they want changed, and is on the First of May.
No. Actually, this saying “May-Day” came from a French word, “M’aidez”. Though they both particularly the same thing, the history behind it is different. It was the idea of Fredrick Mockford who thought it would be a good idea to make “Mayday” an distress call for he heard on the radios French pilots saying “M’aider” which meant “Help me” in an English Translation.
