Nie mam kiedy tego zrobić dziś, ale jutro rano wszystko załatwię.

Yes. Nie mam kiedy literally means I don’t have when, but in natural English it means I don’t have time / I have no opportunity to do it.

In Polish, kiedy can mean not only when? as a question word, but also a time when in expressions like this. So:

• Nie mam kiedy tego zrobić. = I don’t have a time/opportunity to do it.
• Mam kiedy odpocząć. = I have time/a chance to rest.

It is a very natural expression in everyday Polish.

Both are possible, but they are not exactly identical.

• Nie mam czasu = I don’t have time in a general sense.
• Nie mam kiedy = I don’t have a suitable moment / I have no chance to fit it in.

So Nie mam kiedy tego zrobić dziś suggests: Today my schedule is too full; there is no moment when I can do it.

Compare:

• Nie mam czasu. = I’m busy / short on time.
• Nie mam kiedy zadzwonić. = I have no moment when I can call.

English often uses just I don’t have time for both, but Polish can make this distinction more clearly.

Tego is the genitive singular form of to.

In zrobić coś = to do something, the thing done is normally in the accusative. But with negation, Polish very often uses the genitive instead of the accusative:

• affirmative: Mam czas zrobić to.
• negative: Nie mam kiedy tego zrobić.

So tego here corresponds to it/that.

This genitive with negation is very common in Polish, especially with pronouns:

• Widzę to. → Nie widzę tego.
• Mam czas na to. → Nie mam na to czasu.

Because zrobić is perfective, and here the speaker means to get it done / complete it.

• robić = imperfective, focusing on the process: to be doing
• zrobić = perfective, focusing on completion: to do, to finish, to get done

In this sentence, the idea is not just to be doing it today, but to complete it:

• Nie mam kiedy tego zrobić dziś = I don’t have time to get it done today.

If you used robić, it would sound more like the process/activity itself:

• Nie mam kiedy tego robić dziś = I don’t have time to be doing it today.

That version is possible, but it changes the nuance.

Because załatwię is a perfective verb, and perfective verbs in Polish use present-tense forms to express future completed actions.

So:

• załatwiam = I am taking care of / I regularly take care of
• załatwię = I will take care of / I’ll get it sorted out

This is a basic pattern in Polish:

• zrobię = I will do
• napiszę = I will write
• kupię = I will buy

Perfective verbs do not normally have a true present meaning in this form. Their “present” form usually refers to the future.

Not exactly.

Załatwić often means to take care of something, to sort something out, to get something handled. It can sound a bit broader and more practical than zrobić.

So:

• zrobię to = I’ll do it
• załatwię wszystko = I’ll take care of everything / I’ll get everything sorted out

In this sentence, jutro rano wszystko załatwię sounds very natural because it suggests the speaker will handle all the pending matters in the morning.

It is slightly more idiomatic than simply saying wszystko zrobię, although that could also work in some contexts.

Yes, Polish word order is flexible, and dziś could go in different places.

The sentence has:

• Nie mam kiedy tego zrobić dziś

But you could also hear:

• Nie mam kiedy dziś tego zrobić
• Dziś nie mam kiedy tego zrobić

All are understandable. The differences are mainly about emphasis.

Roughly:

• Nie mam kiedy tego zrobić dziś → emphasis falls naturally on today
• Nie mam kiedy dziś tego zrobić → today is inserted earlier, often sounding a bit more neutral
• Dziś nie mam kiedy tego zrobić → strong topic setting: as for today, I don’t have time

Polish word order often reflects focus and emphasis more than strict grammar rules.

Because Polish often uses time expressions like this directly, without a preposition.

• jutro = tomorrow
• rano = in the morning / morning-time

So:

• jutro rano = tomorrow morning

This is completely standard. Similar expressions include:

• dziś wieczorem = this evening
• wczoraj rano = yesterday morning
• jutro wieczorem = tomorrow evening

You do not need w here.

Because ale means but, and in Polish it normally introduces a new clause, so it is preceded by a comma.

Here the sentence has two parts:

• Nie mam kiedy tego zrobić dziś
• ale jutro rano wszystko załatwię

Polish punctuation regularly puts a comma before coordinating conjunctions like ale in such cases.

So the comma is required in standard writing.

Yes, but it would mean something slightly different.

• Nie mam kiedy tego zrobić dziś = I don’t have any time/opportunity to do it today.
• Nie mogę tego zrobić dziś = I can’t do it today.

Nie mogę is broader. It might mean lack of time, but it could also mean lack of permission, ability, or some other obstacle.

Nie mam kiedy specifically points to the scheduling problem: there is no suitable moment.

Wszystko means everything, and it strengthens the promise in the second half.

So instead of just saying:

• jutro rano załatwię — which sounds incomplete unless the object is clear from context,

the speaker says:

• jutro rano wszystko załatwię = tomorrow morning I’ll take care of everything

It gives the idea that all the pending tasks or issues will be dealt with then. It also balances nicely with the first clause: not today, but tomorrow morning I’ll sort it all out.
