Explanation:

The main mealtime in Spain is lunch (la comida, el almuerzo), which usually takes place between 2 p.m. and 3 p.m., has at least two courses and may involve a short half-hour 'siesta' afterwards.

Traditionally in Spanish food culture, comida (lunch in Spain) is the biggest meal of the day, often involving multiple courses. If you go to a restaurant, they usually have a choice of set course lunches, which make up their menu del dia (“menu of the day”). These usually consist of a first plate, drink, then an entree and possibly coffee and dessert. Spaniards eat their lunch, or comida, between 2:00 and 4:00 in the afternoon. Serving as the day's main meal, it is traditionally quite a bit larger than the dinner meal, or cena. A typical lunch will have several courses

At about 6 p.m. people usually have a snack (la merienda) to tide them over until the evening meal at about 9 or 10 p.m., which is lighter than lunch.  the main meal is usually in the evening, after 10 p.m. (la cena).
