Dinner or Supper- What do you call it?

Discussion at the office on a friday:

My youth was split between Texas and Louisiana and what I learned was:

Dinner = Lunch
Supper = Evening meal

"What's for supper?" was what my Pop always asked my Mom when he got home from work.

When I started working summers in my teens (construction), I heard "Dinner time!" when it was lunch time.

What do these words mean?
Dinner, which dates back to the late 1200s, refers to the main meal of the day—historically, a meal served midday for many peoples.

The term comes from the Middle English diner, which, via French, goes back to a Vulgar Latin word represented as disjejunare, meaning “to break one’s fast.” The verb dine also comes from this root.

Supper, in terms of word origins, is associated with the evening. It comes from an Old French word souper, meaning “evening meal,” a noun based on a verb meaning “to eat or serve (a meal).” Fun fact: the word soup, also entering English from French, is probably related. The deeper roots of supper, soup, and related words like sup and sop, appear to be from Germanic roots from way back when.
