I don't have a dish washer or a washing machine or dryer. You'd be amazed how much time doing laundry at a laundry mat for a family of four takes. Or washing dishes by hand for a family of four after every meal.
I also have a full acre of land and only a push mower to mow it with (it takes six hours once a week).
My kids go to a great school, but it's a 45 minute drive in each direction, and no bus from our house.
My husband has Celiac's disease so for the most part all food, cookies, snacks and meals are made by scratch, by me. At the very least I make a cheesecake and two dozen cookies every week, usually more.
My husband works from home and I prepare three meals a day for him, every day. Once a week, maybe, we get take out and I don't have to cook.
I haven't even mentioned how much time I spend vacuuming, picking up, washing floors, scrubbing toilets, removing pet fur from furniture, cleaning liter boxes (three cats), making beds, dusting, taking care of the trash, etc.
Our kids are in school but during the summers and weekends you can add entertaining children (doing arts and crafts, science projects, playing games, etc) to that list.
There's also grocery shopping, banking and managing the finances in there. I pay all our bills, maintain a household budget and basically manage all the money stuff.
My average day stars at 7:30 am and ends at 7:30 pm (when I'm usually done with dinner dishes). As my husband points out (usually when telling me how much he appreciates me) I don't get a lunch hour, sick days, vacation pay or weekends off.
I also do special project things. Stuff that previously we would have paid a contractor for. For example, I removed three carpets and rehabbed the hardwood floors underneath them after we moved into our current house. This took eight hours a day of over a week straight, on my hands and knees with mineral spirits and razor blades to remove the carpet glue without damaging the floor underneath. Doing it myself saved us thousands of dollars.
My husband is very quick to say that I work harder and more than he does, by a good bit, despite him having a full time job.
However, that all being said, I prefer this arrangement to working full time. I'd rather my labors be spent towards bettering my life and my families live than meeting arbitrary goals for a company. I worked at least one job, often two, from the time I was in high school until a year ago.
Technically I have a "real job" too. My husband is a freelancer and he's awful with paperwork. I do all his invoicing. Without me, he quite literally wouldn't get paid (something he points out a lot when I get down on myself).
TL;DR Being a housewife is a full time job, if you want it to be.
