Day of Darkness was the original name of Ireland's D.O.D. Festival. It happened annually in Ballylinan from 2002 to 2008 as a metal music festival. The 2002 line-up was headlined by Primordial. It ran for a second year in 2003. Numbers, however, dwindled that year and a number of changes were implemented before the festival's third running in 2004. In 2005, the festival was moved to the first week in July and has been held on the same weekend each year since. In 2006, a second day was added to the festival and camping tickets were introduced. The festival discontinued in 2008.
