"今天不是星期日。"

Translation: Today is not Sunday.

[ny4MS1qV]

星期日 is mainly used in writing or formal situations. 星期天 just sounds a bit more lively or casual.

[Sam_Oleson]

This is exactly what I was looking for! Xiexie ni!

[VladimirZl13]

谢谢你老板！

[HunorCsaki]

[claudiaw_]

[Ela746448]

[Chu801538]

Yes.

[RoboticBowtie]

why isn't 星期天 used for sunday?

[AxelB.J.Y.M.]

Both words are correct, it is really up to you to use one or the other (or both).

[qTqw8]

It should accept "It's not Sunday today"

[JasperUK]

I had the same problem... Bad programming.

[Brenda532089]

I think my answer "It is not Sunday today" should also be accepted as correct.

[Bluefairypenguin]

Can someone help me pronounce the translation for Sunday? The audio pronounces it very quickly and I can't understand it easily.

[zteen]

It would be xīngqīrì in pinyin, hope that helps!

[Bluefairypenguin]

Yes, that helps! 谢谢你！

[leaningislife]

对，这帮助我，谢谢你。

[JasperUK]

It's not Sunday came up as incorrect! Come on Duolingo, what are you playing at!

[Dinma202095]

Because in the question, the exact translation should be "Todsy is not Sunday"

[Brenda532089]

Is 星期日 same as 星期 天, i.e. Do they both mean Sunday please?

[ovreading]

yes!

[SAGARKHWL]

Sunday is not today should also be an acceptable answer

[Xexelin]

ots not sunday today. is wrong?

[HTGoon]

I always got told this on Mondays.

[Loving_inch]

So we do use 是 with the negative but not with the affirmative?
