1 – Definite Articles with Days of the Week in Portuguese
With days of the week when referring to habitual actions or a specific event occurring on a particular day*
*Sometimes we don’t use an article when we colloquially state what we’re doing on the next-mentioned day relative to when you say it. For example, if in the above sentence, the person had said “Na quinta” instead of “na próxima quinta”, it’s likely that they would have just said, “Quinta vou ao cinema.” (Thursday, I’m going to the cinema). Both ways are considered correct in everyday speech, and which one you use is optional.
