Lughnasadh is the Gaelic name for a harvest festival held on or around 1 August, while Lammas is an English name. Wiccans mark the holiday by baking a figure of the god in bread and eating it, to symbolize the sanctity and importance of the harvest.
The Irish name Lughnasadh is used in some traditions to designate this holiday as the day was traditionally a celebration of the Celtic deity Lugh, hence the name. The name Lammas (contraction of loaf mass) implies it is an agrarian-based festival and feast of thanksgiving for grain and bread, which symbolises the first fruits of the harvest.
