La comida es para el sábado.
though i correctly translated it as "the food is for saturday" i wonder why "el" is used in the sentence?
I think it distinguishes it from "La comida es para los sabados" (pardon my lack of accent), i.e., "The food is for Saturdays". If you have a food that comes back on the menu every Saturday (like Grandma's fruitcake gets recycled every Christmas!) then you would need "los sabados", right?
