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.
For example, in the very south of China, people would usually have an additional meal in the very late evening, after supper. But in the North, we usually have three meals: breakfast between 6.30am-7.30am (depending on people's work schedule), lunch at 12pm to 1pm, and dinner around 7pm.
