The word Halloween is first attested in the 16th century and represents a Scottish variant of the fuller All-Hallows-Even ("evening"), that is, the night before All Hallows Day. Up through the early 20th century, the spelling "Hallowe'en" was frequently used, eliding the "v" and shortening the word. Although the phrase All Hallows is found in Old English (ealra hālgena mæssedæg, mass-day of all saints), All-Hallows-Even is itself not attested until 1556.
Halloween (or Hallowe'en) is an annual holiday observed on October 31, primarily in the United States, Canada, Ireland, and the United Kingdom. It has roots in the Celtic festival of Samhain and the Christian holiday All Saints' Day, but is today largely a 'SECULAR' celebration. It was the vigil or eve before All Saint's Day. And now we have just forgotten the true feast. (The real day of the dead souls is on November the second.) the 31th of October is the eve of All Saint's Day.
All Saints' Day is (in the Roman Catholic Church officially the Solemnity of All Saints) and also called All Hallows or Hallowmass, often shortened to All Saints, is a solemnity celebrated on 1 November in Western Christianity, and on the first Sunday after Pentecost in Eastern Christianity, in honour of all the saints, known and unknown.
Next is All Souls' Day, that commemorates the faithful departed. In Western Christianity, this day is observed principally in the Catholic Church, although some churches of the Anglican Communion and the Old Catholic Churches also celebrate it. The Eastern Orthodox churches observe several All Souls' Days during the year.
We most remember these
Sacred Holidays, and observe it. We're getting lost with each passing year. We need to make a drastic change, for a better tomorrow. We need to get back to the good track, and please God our Father and Creator, so we all can be with Him and he with us, for all eternity.
NOTE: Know what you're celebrating, so you can celebrate it right.
