May Day !!!

Meanings change if we remove a space between the words "MAY DAY" May Day International Workers Day - "May Day" refers to various socialist and labor movement celebrations conducted on May 1, unrelated to the traditional celebrations to commemorate the Haymarket martyrs of 1886 and the international socialist movement generally. The latter event is an important holiday in Communist and Socialist countries. MayDay Mayday is an emergency code word used internationally as a distress signal in voice procedure radio communications, derived from the French m'aider, meaning "help me." It is used to signal a life-threatening emergency by many groups, such as police forces, pilots, the fire brigade, and transportation organizations. The call is always given three times in a row ("Mayday Mayday Mayday") to prevent mistaking it for some similar-sounding phrase under noisy conditions, and to distinguish an actual mayday call from a message about a mayday call.
