LUGHNASADH is nowadays celebrated in August and, like other feasts of the Celtic year, has essentially settled on a specific, unvarying calendar date. Lughnasa, however, although technically associated with the 1st day of August, in practice has moved to various dates in a period from roughly mid-July to the middle of August. Some of the changes resulted from the confusion of changing from Julian to Gregorian calendars, when the 1st of August became the 11th or 12th of August. Many modern reconstructivists prefer to use a particular lunar phase in Leo to decide on the eact date. Niceties over the precise dating of festivals often vary within the factions of human religions and there is no reason to think that the ancient Celtic religion was any different in this respect.
