Thinking about it for a moment, there are more non-leapyears, and more century non-leapyears, I would do:
Code:
  if (iyear % 4) {
    iday = 28;
  }
  else if (iyear % 100) {
    iday = 29;
  }
  else if (iyear % 400) {
    iday = 28;
  }
  else {
    iday = 29;
  }

This will limit the number of if statements executed for a given year.
