In Czechoslovakia, a chair for each living family member and for each family member's spirit are placed by the fireside on Halloween night. In Germany, people put away their knives on Halloween night lest they risk harm to returning spirits.
In Sweden, Halloween is known as Alla Helgons Dag or All Saints Day. A national holiday in historically Catholic countries, All Saints Day it is today a largely secular celebration where people from Spain to Austria, Lithuania to Poland bring flowers, light candles and visit the graves of deceased relatives.
However you celebrate Halloween in your country—trick-or-treating, wearing costumes, honoring the dead, carving jack-o'-lanterns, bobbing for apples, telling ghost stories or other fun and frightening activities—one thing is sure: When it's over, you will already be looking forward to next year.
