"I have time in the afternoon."

Translation: Mam czas po południu.

[AdamMlodoz]

This is accusative so "po południe" gets a "-u" ending?

[Quentin995222]

Why is it sometimes "czas" and sometimes "czasu" with the verb "mam" ?

[Jellei]

Accusative is "czas", Genitive is "czasu".

"mieć" takes Accusative, but when a verb needing Accusative is negated, then it takes Genitive.

Alternatively, you may have seen something like "Mam trochę czasu" (I have some time), "trochę" and other quantifiers like that need Genitive.

... could it be that you are asking about a negative so "nie mam" would take "czasu" as opposed to "mam czas".....

[Garry_S]

may I say: "mam czas po obiadu" ?

[immery]

you can say "mam czas po obiedzie" - which means you have time after "obiad"- so late afternoon/early evening.

[Galois33]

Could you also have 'Mam czas dziś po południu'?

[Jellei]

It's a perfectly fine sentence, but nothing here guarantees that we're talking about dziś = today. Maybe we're discussing next Saturday.

Love it when I find someone else has already asked my question since it means I don't have to wait for an answer

[alik1989]

And we love it when people actually care to read the sentence discussions before asking a question, since it means that we don't need to explain everything 5 times :D

А разве нельзя написать "w południe"?

[Jellei]

Это значит "в полдень" (at noon).

[victoria3216]

In wich case is południe?

[Jellei]

It's Locative. It literally means "after noon" (noon = południe). I think that technically Locative is being introduced in the next skill, but this is just taught as a phrase.
