Bonjour Ann ! You never use the article with "prochain" or "dernier" in French (next/last + durations): "Dimanche prochain, je vais à la plage." "Lundi dernier, j'étais malade." Have a look at our related lesson: https://french.kwiziq.com/revision/grammar/how-to-express-next-last-with-durations-prochain-dernier I hope that's helpful! À bientôt !
