What Time Is Dinner Served in Europe?
Dinner commonly refers to the largest and most proper meal of the day in many Western countries.
Traditionally, the most substantial meal used to be consumed near noontime and called dinner. In Western countries, particularly among the nobility and the wealthy, it slowly migrated to later in the 16th to 19th centuries. The word has various definitions relying on culture and may represent a feast of any size eaten at any period of the day. In particular, it is yet periodically used for a meal at midday or in the early afternoon in exceptional circumstances, such as a Christmas dinner. In countries with hot climatic conditions, people have constantly tended to dine the principal meal in the evening, after the temperature has dropped.
