I assume you mean "How many days is it from the first Wednesday of August to the first Saturday in September?" This interval is 31 full days every year. The day numbers in the months coincide each year, eg. this year 2011 the first Wednesday is the 3rd of August, and the first Saturday is the 3rd of September.
