See the Wiki article Lughnasadh.

Lughnasadh in one of the four main festivals of the Celtic calendar. Lughnasadh was traditionally a time of community gatherings, market festivals, horse races and reunions with distant family and friends. It was also celebrated originally on a date that took solar, lunar and the living signs of the season since it was a harvest festival. Australia Day on 26 February is thus well suited as a date to celebrate Lughnasadh.

On Lughnasadh: "Hail the Thunder God Lugh - Rider of the Storm - Lightning Flashes from his Shining Face". Very appropriate for the Australian Monsoon summer season ! Lugh Lamhfada 'The Shining One of the Long Arm' - the root "lu-" of his name gives us words like luminous and illuminate. Again very appropriate for the fierce sun of the hot Aussie summer. He is the multi-skilled and An Scal in the Land of Paradise (he will come again and save his people). Read Mary Jones article on Lugh:
