# It is garbage day IFF:
# 1) It's Tuesday, and neither Monday nor Tuesday is a holiday, OR
# 2) It's Wednesday, and at least one of Monday or Tuesday was a holiday
FSET garbage_day(x) \
  wkdaynum(x) == 2 && nonomitted(prev_monday(x), x+1) == 2 || \
  wkdaynum(x) == 3 && nonomitted(prev_monday(x), x) < 2
