Allantide (in Cornish Calan Gwaf or Nos Calan Gwaf) is a festival t celebrated on 31st of October . The festival itself seems to have pre-Christian origins similar to most celebrations on this date, however in Cornwall it was popularly linked to St Allen or Arlan a little known Cornish Saint. Because of the this Allantide is also known as Allan day. As in all celtic cultures this time of year was seen as being a significant one and sometimes considered to be the celtic New Year (although this is disputed). In the celtic mind this was the point in the year when the veil between this world and the next was most thin.

Prior to the 20th Century the parish feast of St Just was known as Allantide. Here follows 2 descriptions of Allantide from 19th Century sources.

:"The shops in Penzance would display Allan apples, which were highly polished large apples. On the day itself, these apples were given as gifts to each member of the family as a token of good luck. Older girls would place these apples under their pillows and hope to dream of the person whom they would one day marry. A local game is also recorded where two pieces of wood were nailed together in the shape of a cross. It was then suspended with 4 candles on each outcrop of the cross shape. Allan apples would then be suspended under the cross. The goal of the game was to catch the apples in your mouth, with hot wax being the penalty for slowness or inaccuracy."

THE ancient custom of providing children with a large apple on Allhallows-eve is still observed, to a great extent, at St Ives. "Allan-day," as it is called, is the day of days to hundreds' of children, who would deem it a great misfortune were they to go to bed on "Allan-night" without the time-honoured Allan apple to hide beneath their pillows. A quantity of large apples are thus disposed of the sale of which is dignified by the term Allan Market.
