There are those of us whose dinner time is between 8 and 10 pm most nights! DH comes home NO LATER than 8 pm (well, without calling me, that is ) and I try to have dinner on the table 15-30 minutes later. It's been like this all our married life. Then there's choir night (that's even later--around 9:30, 'cause it's really not good to sing on a full stomach); and singing lesson and Mah Jongg night -- the lesson is 6-7, the game is 7:30-9ish, so no dinner until after--we're lucky if we eat by 8:30 4 nights/week!
I know that for most people in the US, dinner is between 5 and 6:30; we just happen to function later. Of course, we're up until nearly midnight! (And sometimes my 5:45 alarm comes WAY too early!)
