What it is Filled

August 11, day 223 (day 224 in leap years) of the year in the Gregorian calendar, with 142 days remaining in both common and leap years. August 11 is Independence Day in Chad marking 1960 and the anniversary of the solar eclipse of 1999 seen across Europe, of the start of the Watts riots in Los Angeles in 1965 and, as often cited, of the 1973 party in the Bronx widely described as the birth of hip hop.
