Sorry, butt, I don’t know the difference between supper and dinner. To me, they are,the same. You all may guffaw over that butt, I think it is ridiculous...
LOL, the history of the words tells how they were once used.
The main meal for the family was Supper after they came home around 4 to 5.
Dinner, for me , and most in the part of the country where Father's had to work - eight to four - shifts, or some thing similar, was a large meal only on week ends or holidays.
On holidays , but some large families I knew, to keep every one happy on Christmas, would have a large dinner at one house, after church , then later , all would drive to a different families house and have a large supper.
For years, when all of my family was still alive, a small evening supper was also served on holidays at who ever house had that particular holiday.
Sunday after church we had a big dinner
On Saturday, our big meal was still 5 O'Clock supper.
At that up here
Supper Clubs, that usually did not open till around 4 were very common, as they also set their hours for when men came home from work.
Diners that served the farm communities (most were around here), still a few around, usually had hours from 5 till 2 PM.
Farmers would come into the Farm Elevators/Dairys early and often get some thing to eat.
It is still not uncommon among those older than 40 to ask if one wants to go out for a big dinner or later for supper.
