It has been known as Christmas for so long that the original reason for that has been forgotten but the celebration continues, unlike some others, where the name as well as the celebration is lost. A pity, we could do with more excuses for a feast. The beginning of February would be a good day.
*Martinmass (November 11th), "can be documented back to the 14th century and was at that time accompanied “by conspicuous feasting supplemented by musical entertainment”. In England and elsewhere the tradition was to have blood-puddings and freshly roasted meat stemming from the slaughter of what cattle and other animals had to be culled in November. At the same time it was “settling day”, when servants might leave in order to take up new employments. Sat the same time peasants paid their dues to their lords and the tithe to their church; often partly paid in birds like hens, ducks and geese, the tradition grew to eat these birds roasted at the end of autumn and beginning of winter."
*Candlemass (February 2nd*) "Among the Celts, the pagan celebration of Imbolc occurred on the first of February. This was in honor of the goddess Brigid and was associated with purification and fertility at the end of winter. Peasants would carry torches and cross the fields in procession, praying to the goddess to purify the ground before planting.
In churches, the torches were replace by blessed candles whose glow was supposed to take away evil and symbolize that Christ is the light of the world. They would then take the candles to their homes to bring protection to their homes."
and Lammas (loaf mass, to bless the wheat harvest sometime in August) "In many parts of England, tenants were bound to present freshly harvested wheat to their landlords on or before the first day of August. In the Anglo-Saxon Chronicle, where it is referred to regularly, it is called "the feast of first fruits".
