Lammas Day is usually celebrated on the first of August mostly in northern parts of Europe and North America as the celebration of the first wheat harvest and as roughly the halfway point between the Summer Solstice and the Autumnal Equinox. It pre-dates Christianity, but as with many pre-Christian holidays, itís been assimilated into the Christian tradition.
The holiday is traditionally celebrated with the baking of a loaf of bread called Lammas bread from the yearís first harvest. The bread serves as the center of a banquet or fair which also traditionally included lot of games and drinking.
