The Celtic festival wheel is based on a solar calendar divided into four quarters (Solstices and Equinoxes) and cross-quarter days marking the midway points between the quarters. In ancient times, these dates marked the begininning and end of planting and harvesting cycles; the correct marking of time was essential to survival. The importance of the feasts went beyond agriculture, and were tied to important rites of passage- birth, marriage, death- and the life of the community revolved around these dates.
These cycles were associated with deities from the very beginning, and even after Christianity supplanted Paganism in Europe, the holidays were retained with much of their original character.
The eight principal feasts of the Celtic calendar are celebrated by modern Celtic religious groups, and some as folk holidays are still marked in Ireland and Scotland:
Samhain
October 31-November 1
Samhain was
the Celtic autumnal feast. Regarded as the New Year, it was marked with
elaborate feasts for the dead and ritual bonfires.

Arthan, 'light of arthur')
December 21-22
The Winter Solstice marked the birth of the sun and was one of the most
importan t festivals of the year.

( 'in milk')

Candlemas, the Festival of Lights, a Midwinter Festival. Known to Neopagans
and ancient Celts as Imbolc, a festival of the
Maiden Goddess and a traditional time to bless agricultaral implements (especially
