So, let's assume that you've decided to create a routine. How do you do it?
First, it's very important to write it down somewhere that you are likely to see it. If you can't see it, you aren't going to follow it.
Second, list all the chores and how often they need to be done. That will vary from household to household. If you don't have cats, cleaning the litter box realy isn't necessary. If you have 3 kids under the age of 6, you'll be doing laundry more than once a week.
A typical household rouine should cover four weeks.
Start by assigning the daily chores. Then add in the semi-weekly and weekly ones. Put the monthly chores in last. Any chore that doesn't need to be done at least once a month isn't part of a routine.
Don't assign too much to any given day. If you are scheduling 3 hours of routine a day and you work outside the home, you either need to let stuff go or to find help.
Speaking of help, that's the last step: assigning chores. The more regular chores (cleaning bathrooms, doing dishes, vacuuming) can change weekly if you'd like. On the other hand, if you like vacuuming and another person who lives in the house likes ironing (some people do!), why switch? Do what you like. Younger people should start getting chores shortly after they develop sufficient motor skills to walk about the room and turn the TV on. Even a toddler can put her own clothes in the hamper and his toys in the toy box. School age kids can dust and set the table and do dishes. The older a child gets, the more his or her chores should expand beyond the realm of self and into the realm of family. A teen incapable of doing the family laundry or putting a simple dinner (spaghetti and salad) on the table clearly isn't mature enough to have a learner's permit. Driving requires much better motor skills and judgment.
Give your routine a month or two and make notes about what works and what doesn't. Feel free to tweak it to make the routine more usable, remembering that the goal is to have something stable.
Finally, don't be a slave to your routine. If a friend offers you tickets to a Yankees playoff game, you don't say "Sorry, no. Tonight's my laundry night." Instead, you call Elf and ask her how fast she can get to the Bronx.
