Supper vs Dinner. In reality, the difference between supper and dinner is not just cultural, but also a personal definition. Throughout the world, dinner is considered an early meal that is eaten somewhere between 2 pm and 5 pm, while supper is a later meal eaten between 7 pm and 11 pm. This doesnât hold true for all cultures or countries, but it is a relatively safe bet when trying to determine the difference.
Lunch and dinner. So, again, supper survives just as a scrappy, much, much less used alternate word for dinner, the evening meal. It's not so much a semantic difference as a difference in tone and a signifier of place of origin and, to some extent, class. In the South, dinner is eaten at noon and supper is eaten in the evening. In the North, supper is a light evening meal usually eaten either earlier or later than normal.
