Well, if the OP does everything needed for the house, I'd be very surprised if that can be completed in 30mins a day (3.5 hours a week).
Well, I know I manage it - 3.5 hours per week is honestly plenty for housework for three adults, lol.
I can do our shop in about 45mins from leaving home to returning, but I'm quicker than most in that supermarket is close and I shop in Aldi which is quicker than other supermarkets.
I do my food shop online while I'm watching TV in the evenings - hardly arduous or taxing. Yes, doing it in person will take longer but with three adults, someone can do it on the weekend and just alternate it so you're only doing it once or twice month each.
Then, without doing anything complicated let's say 30mins on average to prep a meal each day (Yes, there are some things I can do in less, but there are others that take longer) - well that is 3.5 hours on it's own.
I don't count cooking dinner as housework - it's just part of what you have to do to sustain yourself. It's something that should be evenly split between the three working adults in the house.
So where are you counting all the following:
Now, I'm fairly slovenly compared with many on MN, but say you vacuum a whole house once a week.... clean toilets / shower /bath....the odd bit of dusting once a fortnight / mopping hard floors and lino.....
I vacuum daily, clean the loo daily, rinse the shower out after every use (as does DH), sweep the hard floors daily and mop once a week. It barely takes any time if you do it daily as it never has the chance to build up.
add in the 'occasional' jobs - defrosting the freezer once a year.....cleaning the oven every couple of months..... cleaning the fridge......cleaning woodwork round the house......all the stuff like putting up then putting away Christmas decs......cleaning windows.....taking care of plants......
Well, I don't have plants, I wipe the fridge weekly before the food shop comes and I can't say I've ever cleaned a window or a skirting board in my life. The window cleaner does the windows and I vacuum the skirting boards when they start looking mucky. I can't say I've ever cleaned an oven in my life, lol.
Then sorting paperwork....finding best prices for insurance, utilities etc
I'd say that takes me maybe two hours a year, if that? Bills are on direct debit and when I get an e-mail saying insurance is up for renewal, I'll either just let the policy renew or spend half an hour on a price comparison site somewhere.
Oh, and the daily stuff of washing up or loading / unloading dishwasher...wiping down surfaces and so forth?
Again, I do that daily and it only takes 10-15 minutes a day split over the day. We also don't have a dishwasher so everything is washed by hand.
Laundry and all that entails - no, not much on it's own for 3 adults, but still starts adding up (with everything else) to a lot more than 30mins a day.
Again, it takes two minutes to put clothes in a machine and press a button, and another five minutes at the end of the drying cycle to unload and put it away. What are people doing that makes it take so long?
If the OP's dh does nothing, then the OP is definitely doing a LOT more than 30mins a day
And if she is, that's by choice, not necessity. But I'm of the school of thought that housework expands to fill the amount of time you have. If you only have thirty minutes, you can get a surprising amount done in that time if you actually focus and don't let yourself get distracted.
