Halloween, or Hallowe'en (a contraction of All Hallows’ Evening), also known as Allhalloween, All Hallows' Eve, or All Saints' Eve, is a celebration observed in a number of countries on 31 October, the eve of the Western Christian feast of All Hallows' Day. It begins the three-day observance of Allhallowtide, the time in the liturgical year dedicated to remembering the dead, including saints (hallows), martyrs, and all the faithful departed.
A sailor, seaman, mariner, or seafarer is a person who navigates waterborne
vessels or assists as a crewmember in their operation and maintenance.
The term bluejacket may be used for British or US Navy enlisted sailors,
the latter especially when deployed ashore as infantry.
Etymologically, the name "sailor" preserves the memory of the time when ships were commonly powered by sails, but it applies to the personnel of all vessels,
whatever their mode of propulsion, and includes military (naval) and security (coast guard) maritime personnel and members of the merchant marine, as well as recreational sailors.
The term "seaman" is frequently used in the particular sense of a sailor who is not an officer.
