At the end of which season the daughters of Airitech would come out of the Cave of Cruachan every year?
Samhain Samhain (pronounced or , ] ) is a Gaelic festival marking the end of the harvest season and the beginning of winter or the "darker half" of the year. Traditionally, it is celebrated from 31 October to 1 November, as the Celtic day began and ended at sunset. This is about halfway between the autumn equinox and the winter solstice. It is one of the four Gaelic seasonal festivals, along with Imbolc, Bealtaine and Lughnasadh. Historically, it was widely observed throughout Ireland, Scotland and the Isle of Man. Similar festivals are held at the same time of year in other Celtic lands; for example the Brythonic Calan Gaeaf (in Wales), Kalan Gwav (in Cornwall), and Kalan Goañv (in Brittany).
Reek Sunday Reek Sunday (Irish: "Domhnach na Cruaiche" ) or Garland Sunday is an annual day of pilgrimage in Ireland. On the last Sunday in July, pilgrims climb Ireland's holiest mountain, Croagh Patrick (764 metres) in County Mayo. It is held in honour of Saint Patrick who, in the year 441, spent 40 days fasting on the mountain. Masses are held at the summit, where there is a small chapel. Some climb the mountain barefoot, as an act of penance, and some carry out 'rounding rituals', which were formerly a key part of the pilgrimage. This involves praying while walking sunwise around features on the mountain. They walk seven times around the cairn of Leacht Benáin (Benan's grave), fifteen times around the circular perimeter of the summit, seven times around Leaba Phádraig (Patrick's bed), and then seven times around three ancient cairns known as Reilig Mhuire (Mary's cemetery).
