Questions & Answers about Dimarts no treballo, així que aniré a la biblioteca.
In Catalan, days of the week are often used without a preposition when they express time.
So:
- Dimarts = Tuesday / on Tuesday
- Dilluns = Monday / on Monday
That is very normal Catalan.
A useful contrast:
- Dimarts no treballo = On Tuesday, I’m not working / Tuesday I don’t work
- Els dimarts no treballo = I don’t work on Tuesdays (habitual, every Tuesday)
So in your sentence, Dimarts refers to a specific Tuesday, not a repeated habit.
Yes — in Catalan, weekdays are normally lowercase:
- dimarts
- dimecres
- dijous
Here it is capitalized only because it is the first word of the sentence. If it appeared in the middle, you would usually write:
- No treballo dimarts.
So Catalan is like English at the start of a sentence, but unlike English in general usage, because weekdays are not usually capitalized.
