The date of Halloween is associated with the Celtic festival of Samhain, which was celebrated by the Celts as the end of the harvest season and the start of winter.
It is believed that the dead return to walk among the living on this day, so people dress up in costumes to remind them of their mortality.
The date of Halloween is celebrated on the day before All Saints' Day, which is a day of remembrance for the Christian Church. Halloween is always celebrated on October 31.
The Christian Church later declared Samhain as the day when people died and went to heaven, based on the belief that people and animals returned to the land of the dead on that day.
It was the day to avoid practicing witchcraft and to have masses for the dead. Today, many people celebrate Halloween as a fun night of trick-or-treating and costume parties.
Many people make pumpkins on Halloween for several reasons, including decoration, as a food item, or for Halloween parties.
Some people carve pumpkins for Halloween, while others make jack-o'-lanterns. Some people even make jack-o'-lanterns out of real pumpkins.
