"Halfway" is an
Irish-American holiday, short for "Halfway to St. Patrick's Day." It is celebrated annually on
September 17. It can also be celebrated as Halfway to Unofficial. It is most often celebrated where there are high concentrations of Irish-Americans, such as Illinois, Ohio, and Minnesota, but Celtic clubs and pubs in other states are continuing the trend by hosting 5k runs, barcrawls, or
Irish music concerts.
