"Det är viktigt att använda samma kalender."

Translation: It is important to use the same calendar.

[Arnauti]

The new TTS says kalender right.

[Papanash]

why isn't this "Det är viktigt att använda den samma kalendern"

[Zmrzlina]

The adjective samma cannot be definite, so its noun is always indefinite.

Very interesting sentence in a Swedish course: see https://en.wikipedia.org/wiki/Swedish_calendar or https://sv.wikipedia.org/wiki/Svenska_kalendern.

So for the select from a wordbank options I had both "is" and " 's" to choose from. I went with " 's" to make "It's" which was marked as a typo. Last I checked "it's" is a contraction of "it is" and therefore should be wholely correct just the same as "it is", and not be considered a typo.

Kalender is not definite then why "the" we use in translation?

[Maddis31]

Russians: No.

Why is the same agenda not correct?
