"It is a long day today."

Translation: Dziś jest długi dzień.

[eggdropsoap]

Not „Dziś to długi dzień”?

[immery]

dziś is an adverb.

[eggdropsoap]

And „to” cannot be used with adverbs?

[wladzimirpucin]

To is not a verb, while jest is a form of the verb, być (to be.)

[gbaldacci1309]

this was very confusing. The English sentence should read: "Today is a long day" for this exact translation...not "It is a long day today". I would never have come up with this Polish translation with the way the English sentence was written.

Agreed, I also think "Today is a long day" is better, I made it the default answer.
