At our house, it was breakfast, dinner, and supper. Reminds me of the time we were invited to a friend of my dad's house, to come to dinner on a Sunday. We hurried home from church after Sunday School, changed clothes, then drove 50 miles to the friend's home. We were very hungary, but we had to wait until 6:00 p.m. to eat because the friend was English and his wife was Irish....Dinner was in the evening, and they entertained us until then. Their kids were brats, and all 4 of us kids were expected to be angels. And for the most part, we were. I don't remember any of us getting in trouble that day.

Growing up it was breakfast, lunch, and supper. Dinner was a meal cooked for Sunday after church and for holidays.. Christmas Dinner, Thanksgiving, Easter, New Years, Birthdays.

In Louisiana dinner was at noon and supper was at night. Now I've gotten used to saying lunch and supper.

Always called breakfast, lunch and supper in our steel mill town.

For us, it was breakfast, then lunch.
Dinner and supper (the words) were interchangeable. We just knew that when one or the other was used that it was the evening meal.

Breakfast (before school started or in the summer, whenever we got up )- -Lunch(12:00 noon)- - Supper (ALWAYS at 5:15P...Never at 5:14 or 5:16...ALWAYS at 5:15P)...my father was a Time Study Engineer.

For special occasions, Easter, Thanksgiving, Christmas it was called dinner.

Same here, breakfast, dinner and supper, lunch was the mobile meal on the farm

Same at my house growing up in a small Arizona town. This is an interesting chat. It seems like the terms would be more regional than it appears here. DH grew up calling them breakfast, lunch, and dinner. Now that we are retired we eat breakfast soon after getting up in the morning, then we eat dinner sometime between noon and three, and maybe a little snack around five.

Same in my old neighborhood in W.Va.'s northern panhandle. What about "school lunch" and "lunch bucket" and "lunch counter" and "dinner bell" or "dinner pail"? Perhaps it's a country folks/working class thing vs everyone else?
The Bible translates a lot of times as "meal" but the Lord and the disciples shared a last "Supper."

Go back to the nineteenth century and be asked to "sup", "dine", "repast", "bait", "luncheon"....
