I work evenings, so it's to bed between 3:30am and 4am, and up at 10:00am to 10:30am. Average about 6 1/2 hours.
Ah, the old grave-yard shift (if one works shift work), I hated the afternoon shift, but the grave-yard from twelve to eight was nice only in that no big shot was around, and the shift foreman was a decent dude.
Years later I worked at Cabinet shop graveyard shift, straight nights from at first 2 to 2 then when business dropped, from 2 to 10 Monday thru THursday.
One kind of good thing was when I headed home at 2, the grocery store was a 24 hours place and you could smell the next batch of goodies being baked.
I would stop at the grocery store and bring home baked goods for my kinda-sorta breakfast.
One of those odd pleasant memories.
