"Tirsdag er en hverdag."

Translation: Tuesday is a weekday.

[JegHeterKordian]

Isn't it a mistake? Hverdag means "everyday".

[griffindd]

hver dag = every day; hverdag = a working day

[JegHeterKordian]

Wow! Another mind blown. Takk !

[Ingebj]

In a few situations I would say you could safely translate hverdag to "everyday". Example: "Han har en vanskelig hverdag" would be understood as similar to "His everyday life is hard/difficult".

[montajndju]

Are you sure you write it without space between hver and dag?

[Ingebj]

Hverdag is without space between the two words unless you want to say every (single) day. See comment by Griffindd where the usual translations are given.

[Danuta_Grazynka]

Do Norwegians actually use "hverdag" as "a working day"?
I have always used "en abreidsdag" (as a working day) and "hverdagen" (as everyday/daily life). I guess it's not a mistake, but I'm wondering what is more common?

Is tirsdag supposed to be pronounced tishdawg?

[kirstm]

No. It is supposed to be pronounced: "tirshdag". The "r" sound won't be completely muted, you ought to pronounce both "r" and "rs" sounds.
