The Samhain celebrations have survived in several guises as a festival dedicated to the harvest and the dead. In Ireland and Scotland, the Féile na Marbh, the 'festival of the dead' took place on Samhain.
The night of Samhain, in Irish, Oíche Shamhna and Scots Gaelic, Oidhche Shamhna, is one of the principal festivals of the Celtic calendar, and falls on the 31st of October. It represents the final harvest. In modern Ireland and Scotland, the name by which Halloween is known in the Gaelic language is still Oíche/Oidhche Shamhna. It is still the custom in some areas to set a place for the dead at the Samhain feast, and to tell tales of the ancestors on that night.
Traditionally, Samhain was time to take stock of the herds and grain supplies, and decide which animals would need to be slaughtered in order for the people and livestock to survive the winter. This custom is still observed by many who farm and raise livestock because it is when meat will keep since the freeze has come and also since summer grass is gone and free foraging is no longer possible.
Bonfires played a large part in the festivities celebrated down through the last several centuries, and up through the present day in some rural areas of the Celtic nations and the diaspora. Villagers were said to have cast the bones of the slaughtered cattle upon the flames. In the pre-Christian Gaelic world, cattle were the primary unit of currency and the center of agricultural and pastoral life. Samhain was the traditional time for slaughter, for preparing stores of meat and grain to last through the coming winter. The word 'bonfire', or 'bonefire' is a direct translation of the Gaelic tine cnámh. With the bonfire ablaze, the villagers extinguished all other fires. Each family then solemnly lit its hearth from the common flame, thus bonding the families of the village together. Often two bonfires would be built side by side, and the people would walk between the fires as a ritual of purification. Sometimes the cattle and other livestock would be driven between the fires, as well.
Divination is a common folkloric practice that has also survived in rural areas. The most common uses were to determine the identity of one's future spouse, the location of one's future home, and how many children a person might have. Seasonal foods such as apples and nuts were often employed in these rituals. Apples were peeled, the peel tossed over the shoulder, and its shape examined to see if it formed the first letter of the future spouse's name. Nuts were roasted on the hearth and their movements interpreted - if the nuts stayed together, so would the couple. Egg whites were dropped in a glass of water, and the shapes foretold the number of future children. Children would also chase crows and divine some of these things from how many birds appeared or the direction the birds flew.
