Lammas, also known as Lughnasadh, is a traditional festival celebrated on August 1st (or thereabouts) in the Northern Hemisphere and February 1st in the Southern Hemisphere.

Lughnasadh is a pagan holiday associated with the god Lugh (Lú) in ancient Celtic mythology, and one of the eight Wiccan sabbats during the year. 

The name "Lammas" is derived from the Old English term "hlafmaesse," which means "loaf mass" and emphasizes the importance of the first wheat harvest and offering loaves of bread to the church.

Lammas is one of the four Gaelic seasonal festivals of the Celtic calendar and marks the beginning of the harvest season. It is a cross-quarter day, falling halfway between the summer solstice (Litha) and the autumn equinox (Mabon).

Lammas is also known as  Lughnasadh, (pronounced "LOO-nah-sa), a pagan holiday associated with the god Lugh (Lú) in ancient Celtic mythology, and one of the eight Wiccan sabbats during the year.
