A medieval feast does not mean a meal.
The medieval idea of a feast was a whole day spent celebrating a particular Saint, with special church services (often starting in the evening before the feast day) and with particular types of food traditionally eaten. In the churches and monasteries special hymns would be sung and the story of the Saint would be read out. Feast days punctuated the calendar and enabled people to specify a particular date: "I have to pay my rent on the Feast of St Michael", or "Our daughter was born two days before the Feast of Saint Martha, so we named her Martha".
The word feast comes from Latin dies festus, meaning a solemn day.
You probably mean a banquet, which might go on for many hours.

You need to specify which particular country you mean: Spain? Sicily? Egypt? Germany? Scotland? You also need to specify what years you are interested in.
