Halloween is celebrated on the night of October 31 and it is believed that it has pagan roots. The customs may be influenced by folk folk customs and beliefs from the Celtic-speaking countries. The theory that is the most popular says that the celebration comes from ancient Celtic harvest festivals, particularly the Gaelic festival Samhain.

Like many other celebrations, it is believed that the Samhain festival was Christianized by the early Church but others claim that it may have been Christian from the start. It is difficult to say as it evolved through many centuries and nobody held records of these kinds of things. 

The Samhain festival marked the end of the harvest season and it meant the beginning of winter, when more than half of the day was dark so it was also a mysterious time. It was believed that on the day of the transition the boundaries between this and the other world would be less defined. 

People believed that at this time spirits could enter their world and among gods, fairies and demons, their lost relatives could come to their home too. That is where all the treats come from as people would make a big dinner out of the harvest to make the spirits feel welcomed. 

The Christian influence can be seen in the tradition that many Church festivities would start the day before, on the vigil as Halloween is the evening before the Christian holy days of All Hallows' Day on 1 November. That is where the name of Halloween actually comes from. 

If the pagans believed that the October 31 night is when spirits come to Earth in Christian tradition it is explained that on that day people should spend time honoring the saints and praying for the recently departed souls who have yet to reach Heaven. 

Halloween didn’t become widely celebrated in North America until the 19th century when Irish and Scottish mass immigrated to the continent. Over time it evolved to this huge holiday that we see now and its influence can be felt all over the world.

Even though it was commercialized in modern times Halloween is not a superficial festivity without no meaning and created just for fun. It has some meaning to it and it has analogues in other countries too when the dead are honored and in some countries people will just light a candle, go to church or cemetery and in others they will celebrate this occasion with more bang and pizzazz.
