The tradition of Halloween on the 31st of October comes from the ancient Celtic festival of Samhain. Samhain was the Celtic New Year and they celebrated it on the 1st of November because that was the end of summer and harvest time (life) and the beginning of winter (death). It was also the time for ghosts to return to earth for a day. People lit a big fire, wore special clothes made of animal skin and hoped to be safe from ghosts and winter. In AD 609, the Catholic Church put the Christian celebration of All Saints Day on the 1st of November. In AD 1000, the church added All Souls Day on the 2nd of November, and All Hallows Eve – or Halloween – moved to the night of the 31st. Under the wizardry ot the English teacher Marta Fernández, 1st BTX students reviewed this ancient celtic tradition with a terrifying escape room.
