I work 8:30am - 5pm Monday to Friday, however as I get up at 7:30 and don't get in the house till 6 pm I see my working day as 7:30am - 6 pm. Also it takes me 30 minutes or so to actually get to sleep once I get into bed, as my brain needs to switch off, also I can't go a whole night without waking up randomly a few times atleast.
So with that in mind =
Mon - Fri = 7:30am to 6pm work, 12pm - 7:30am sleep.
Saturday + Sunday usually sleep for 8 - 10 hours unless I have an early morning planned.
