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.
The distinction between dinner and supper was common in United States farming communities into the twentieth century. In most parts of the United States and Canada today, supper and dinner are considered synonyms (although supper is a more antiquated term). In Saskatchewan, and much of Atlantic Canada, supper means the main meal of the day, usually served in the late afternoon, while dinner is served around noon.
