There's two ways to celebrate this day:
If you normally do the housework around the house, cease and desist for this day. Instead, kick back and enjoy the day. Relax and do anything, except housework.
If you are a spouse or significant other, do the housework for your mate. It gives her (or him) a break from the housework. And, you just might get an appreciation of how much work it takes to keep up the house.
