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.
However, the term dinner can have many different meanings depending on the culture; it may mean a meal of any size eaten at any time of the day. Historically, it referred to the first meal of the day, eaten around noon, and is still sometimes used for a noon-time meal, particularly if it is a large or main meal.
