"Dziś jest czwartek."

Translation: Today is Thursday.

[Tom873317]

Why not dzisiaj?

[vytah]

While it's less common in this kind of contexts, it's correct. Have you reported it?

[Tom873317]

Well, it was just part of the question, not a rejected answer, so I didn't report it. But is there a difference? I've always seen dzisiaj in other vocab references. When would one be preferred over the other?

[gebo513]

When I was in Polish school the teacher always used "Dzisiaj jest...". I also would like to know what the difference is. Maybe dzisiaj is more formal?

[immery]

I am a Polish native speaker and had no idea if there is a difference, so I checked

they say dziś rhymes with different words then dzisiaj. :)

[va-diim]

Why is neither dziś nor czwartek in instrumental case with być as the verb here?

[immery]

dziś is adverb.

[fred149559]

What about czwartek ? It should be instrumental no ?

[Jellei]

No. Instrumental is used for Y in "X is Y" sentences if both X and Y are noun phrases.

"Dziś" is an adverb, so that rule doesn't apply.

[fred149559]

Oh ok thanks !

[Xavier.e0628]

Today is Thursday right now!

[HarveyPenf1]

what is the difference between dziś and dzień??

[Jellei]

Well, the first one means "today" and the second means "a day" ;)

[JayLu24]

Nie, dziś jest piątek

[NathanGask3]

So the word Dziś is an adverb. Does that it has no tense or gender? If not, what is the tense or gender?

[alik1989]

Yes, it's an adverb and adverbs have neither tense nor gender in Polish.
