"På lørdag er det helg."

Translation: On Saturday it is the weekend.

[UtkarshSyng]

Could "helget" be used instead of "det helg"?

[quis_lib_duo]

No, as helg is masculine, the definite form is helgen. Here, det means it and is not the article.

[UtkarshSyng]

Got it!

[Athalawulfaz]

Because the verb must be in second position, 'på lørdag er det helg' ('på lørdag' taken as one because of it being a preposition phrase) is literally 'on Saturday is it weekend' but the definite article is not needed here.

Why not det er helg?

[beerzoe]

Because the verb goes in the second position in Norwegian.
