How 80/20 adds up

  • 3 of 14 nights is 21%, so every other weekend from Friday to Monday gives 79/21.
  • Every other weekend from Friday to Sunday is 2 of 14 nights, 86/14.
  • Over a year that is about 78 nights with parent 2 for Friday to Monday, or 52 for Friday to Sunday.
  • Many families add a weeknight dinner, which doesn't change the overnight count.
