I would like to ask why in the first sentence 'à Pâques' is not correct and it is translated 'pour Pâques' instead. According to this lesson (Which prepositions to use with celebration days - like Christmas - in French) the preposition should be 'à'. Are there other situations?
Also, why is there the article in '... pour déjeuner le dimanche' if it refers to a specific Sunday? (Using "le" with days of the week + the weekend (French Definite Articles))
Thank you
