OK, sorry, I missed a few pages!
From your original post I asumed you meant day to day stuff.
No, I would not be able to fit the non day to day stuff in, we do a lot of that at the weekend.
I would say big garden stuff, redecorating, holiday planning, basically anything not day to day wouldn't really fit.
Although, my Mum told me if you have a big job to do (eg paint a room), don't do all the daily stuff first, the minnute the kids are out of the door, go and do 3-4 hours on your big job. The breakfast stuff and dishwasher will get done around everything else, but a big job won't. This is actually very clever, and worked very well, so at times, I have taken a few days to do this, and the everyday stuff gets done round it.
I have sympathy, because I think your issue is really that you are not working as a team. But you do have a huge amount of time.
