“All Hallow’s Eve” is the eve before the religious feast All Saints (aka All Hallow’s Day), remembering the dead, saints and martyrs of christianity. Many of the traditions of Halloween are believed to originate in ancient Celtic harvest festivals and pagan traditions. It was mainly Irish immigrants to the USA who brought along the many more secular traditions like trick-or-treating, Halloween costume parties, carving pumpkins into jack-o’-lanterns and lighting bonfires.
While in Europe All Saints was mainly celebrated in the religious sense (remembering the dead, lighting candles at their graves), in the last ten years the more “American” way of celebrating Halloween became more popular into what is now a big commercial business for retail.
That said, I still have some candy at home in case there are some trick-or-treating kids at the door (which happens less and less as our own kids and their friends are grown beyond collecting candies) and watch a good classic horror movie in the darkened living room.
I wish all of you a very creepy Halloween (stay safe noneless)
