Lammas is a Neo-Pagan holiday, often called Lughnasadh, celebrating the first harvest and the reaping of grain. It is a cross-quarter holiday halfway between the Summer Solstice (Litha) and the Autumnal Equinox (Mabon). In the northern hemisphere, Lammas takes place around August 1 with the Sun near the midpoint of Leo in the tropical zodiac, while in the southern hemisphere Lammas is celebrated around February 1 with the Sun near the midpoint of Aquarius.
In some English-speaking countries in the Northern Hemisphere, August 1 is Lammas Day (loaf-mass day), the festival of the wheat harvest, and is the first harvest festival of the year. On this day it was customary to bring to church a loaf made from the new crop. In many parts of England, tenants were bound to present freshly harvested wheat to their landlords on or before the first day of August.
Lughnasadh (pronouced loo'nass'ah) comes at the beginning of August. It is one of the Pagan festivals of Celtic origin which split the year into four.
The reason for this info, because I was born on Lammas day!
