Lughnasadh, sometimes called Lammas, is a pagan holiday celebrated half way between the summer solstice and fall equinox, typically around August 1st for the northern hemisphere.
This holiday derives it's name from the assembly ("násad") of worshipers of Lugh, the celtic god of light. The alternate name Lammas, is derived from Old English words for "loaf mass" and references the harvest of grains during this time of year along with the many loaves of bread that come from it.
Pagans around the world celebrate this first harvest festival as this is when many crops deliver their fruits. It's common to bake Lammas bread and cakes, feast and hold games to celebrate the bountiful rewards of their labors. Fitting for it's position in the height of summer, this festival is ruled by fiery golds, yellows and reds.
