Ósmego października mamy rodzinny obiad u babci.

Because in Polish, dates are usually expressed with the ordinal number in the genitive case.

So:

• ósmy = eighth as a basic dictionary form
• ósmego = of the eighth, which is the form used in dates

In this sentence, Ósmego października means on the eighth of October.

This is a very common pattern:

• pierwszego maja = on the first of May
• trzeciego lipca = on the third of July
• dwudziestego grudnia = on the twentieth of December

So even though English says October eighth or the eighth of October, Polish uses the genitive forms for the date.

For the same reason: in Polish dates, the month name also appears in the genitive case.

• październik = October
• października = of October

So:

• Ósmego października literally corresponds to of the eighth of October, but naturally means on the eighth of October

This is standard with all months in dates:

• 1 maja
• 5 czerwca
• 12 listopada

It means on October 8th in this sentence.

Polish often uses the bare date expression without needing a separate word for on. So:

• Ósmego października mamy rodzinny obiad = On October 8th we have a family dinner/lunch

The idea of on is built into the date expression.

Because Polish word order is flexible, and putting the date first is very natural when you want to set the time frame right away.

• Ósmego października mamy rodzinny obiad u babci.
  = On October 8th, we have a family meal at Grandma’s.

You could also say:

• Mamy rodzinny obiad u babci ósmego października.

Both are grammatical, but starting with the date often sounds more natural when giving schedule information.

Mamy is the 1st person plural form of mieć = to have.

So:

• mam = I have
• masz = you have
• ma = he/she/it has
• mamy = we have

In this sentence:

• mamy rodzinny obiad = we have a family meal

This can mean:

• we are having one
• one is planned
• it is scheduled

So it often sounds a bit like we’re having in English.

This is a very common question because meal words do not match perfectly between Polish and English.

Obiad traditionally means the main meal of the day, often eaten in the afternoon, so it is often closer to:

• lunch
• midday meal
• sometimes dinner, depending on the family and context

So rodzinny obiad could be translated as:

• a family lunch
• a family dinner
• a family meal

The exact English translation depends on when the meal happens and how the family thinks about it.

Rodzinny means family or family-related.

So:

• rodzinny obiad = a family meal / a family dinner/lunch

It suggests that this is not just any meal, but one involving family members, often with a warm or traditional feeling.

Grammatically, rodzinny is an adjective agreeing with obiad:

• obiad is masculine singular
• so the adjective is rodzinny in masculine singular form too

Because u is the normal preposition used when you mean at someone’s place/home.

So:

• u babci = at Grandma’s / at Grandma’s house
• u mamy = at Mom’s
• u kolegi = at a male friend’s place
• u lekarza = at the doctor’s

Using w here would not work for the meaning at Grandma’s house.

So u babci is the natural Polish way to say at Grandma’s.

Because the preposition u requires the genitive case.

• babcia = grandmother / grandma
• babci = of grandma / at grandma’s, after u

So:

• u babci = at Grandma’s

This is a fixed and very common pattern:

• u cioci = at auntie’s
• u siostry = at sister’s
• u Tomka = at Tomek’s

Usually, yes, but the tone matters.

• babcia is a warm, familiar word: grandma, gran
• babci is just the case form used here

So u babci usually means at Grandma’s in a personal, family sense.

If you wanted a more formal word for grandmother, Polish also has babka, but that is different in tone and usage and can even mean other things in some contexts. For everyday family speech, babcia is the normal word.

Yes, absolutely.

That is a very natural English translation.

Polish mamy often corresponds well to English we are having when talking about planned events:

• Ósmego października mamy rodzinny obiad u babci.
• We are having a family dinner/lunch at Grandma’s on October 8th.

That translation sounds more natural in English than a very literal we have.

Normally, no.

In Polish, names of months are usually written with a lowercase letter, unlike in English.

So:

• październik
• października

not Październik or Października, unless the word begins a sentence for normal capitalization reasons.

In your sentence, Ósmego is capitalized because it is the first word of the sentence, not because dates are normally capitalized in some special way.

A common numeric form would be:

• 8 października
• 8.10
• 8.10.
• 08.10.

If you include the year:

• 8 października 2026 roku
• 08.10.2026

When spoken aloud, however, Polish usually uses the genitive date pattern, like:

• ósmego października

So the written number 8 is typically read as ósmego in this context.
