Whenever it is necessary to compute the average daily attendance of a school of a district for any certain purpose and no provision is made for the computation thereof for such purpose, the average daily attendance of the school shall be computed by dividing the total number of days of pupil attendance allowed by the number of days school was actually taught in the regular day schools of the district, exclusive of Saturdays or Sundays.
