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.
Dinner was the one meal the Romans did eat, even if it was at a different time of day. In the UK the heyday of dinner was in the Middle Ages. It was known as cena, Latin for dinner. The aristocracy ate formal, outrageously lavish dinners around noon.unch. The terminology around eating in the UK is still confusing. For some lunch is dinner and vice versa. From the Roman times to the Middle Ages everyone ate in the middle of the day, but it was called dinner and was the main meal of the day.
