Months in Polish: All 12, and Why Only Two Come From Latin

Ten of the twelve are not Latin at all

English months are Roman almost without exception. January is Janus, March is Mars, July is Julius Caesar, August is Augustus, and September through December are simply the numbers seven to ten, left stranded two months out of place by a calendar reform nobody bothered to tidy up afterwards.

Polish kept something older. Ten of its twelve months are Slavic words describing what is actually happening — what is flowering, what is being cut, what is falling off the trees, what the ground is doing. Only two were borrowed from Latin: marzec, from Martius, and maj, from Maius.

Which means that for ten months of the year, a Pole saying the date is describing the weather.

All twelve, spoken

What each one is actually describing

Styczeń is the joining — the seam where one year meets the next.

Luty is an old adjective meaning fierce or savage. It survives in modern Polish almost nowhere else, and it is describing the cold.

Kwiecień is from kwiat, flower. April is the flowering.

Czerwiec is from czerw, the Polish cochineal — an insect harvested in June and crushed for a red dye that was a genuine medieval export. The Polish word for red, czerwony, comes from the same creature.

Lipiec is from lipa, the linden tree, which blossoms and fills whole streets with scent in July.

Sierpień is from sierp, the sickle. Harvest.

Wrzesień is from wrzos, heather, which turns the moorland purple in September.

Październik is from paździerze, the woody waste left when flax is broken for its fibre — the least romantic and most honest of the twelve.

Listopad is liść plus padać: leaf-fall.

Grudzień is from gruda, the frozen clods of earth you get when the ground hardens.

The trap: listopad is not November everywhere

Several Slavic languages kept these nature-names, which makes them look reassuringly familiar to each other. They are not always pinned to the same month.

Polish listopad is November. Czech listopad is also November. Croatian listopad is October.

So a Croatian and a Pole can read each other’s calendar, agree on what the word means, and still be a month apart. If you are working with records from more than one Slavic country — which many families with roots in the old borderlands are — this is worth knowing before you write a date into a family tree.

Saying when something happens

Polish marks “in” on the noun itself rather than leaning on the preposition, so the month changes shape. Styczeń becomes w styczniu. And dates use a different ending again: maj becomes maja, so the first of May is pierwszy maja.

Saying these out loud

The stress is almost always second-to-last. paźDZIERnik, liSTOpad, STYczeń. Polish is extremely regular about this, and once you trust it you stop having to think.

A final d hardens to a t. Listopad is lees-TOH-paht. The letter stays soft on the page and not in the mouth — the same rule that turns już into yoosh.

w is a v, until it is an f. In front of a voiceless sound it hardens: w styczniu is f STICH-nyoo, but w lutym is v LOO-tim. You do not have to memorise which — say it fast and your mouth does it for you.

rz is a zh, the s in “measure”. Marzec is MAH-zhets, and the final c is a ts, never a k or an s. Every one of the extra letters is spoken on our Polish alphabet page.

Seasons, and the words a record actually uses

Reading a date in a Polish parish record

If you are working back through Polish records — and a great many people reading this page are — the months are not the hard part. The endings are.

A nineteenth-century baptism entry does not say 3 maj 1897. It says something much closer to dnia trzeciego maja tysiąc osiemset dziewięćdziesiątego siódmego roku — on the third day of May of the year one thousand eight hundred ninety-seven. Everything is spelled out, and everything is inflected.

What to look for. Dnia opens the date — “on the day of”. The month appears in the genitive, so maj becomes maja, styczeń becomes stycznia, listopad becomes listopada. And roku closes it — “of the year”.

The genitive forms, so you can recognise them: stycznia, lutego, marca, kwietnia, maja, czerwca, lipca, sierpnia, września, października, listopada, grudnia. Several change more than you would expect — luty becomes lutego because it behaves like an adjective, which it originally was.

And the language may not be Polish. Depending on the partition your family lived under, records from the same village might be in Latin, Russian or German rather than Polish. Latin months you will recognise on sight. Russian ones are in Cyrillic and are the Latin names again. It is Polish that looks unfamiliar, which is the opposite of what most people expect.

Two more things worth knowing

The stress never moves. Polish puts it on the second-to-last syllable with real consistency, and the months are no exception: paźDZIERnik, liSTOpad, STYczeń, gruDZIEN. Once you stop looking for exceptions you stop making mistakes.

Lato means summer, and also year. Modern Polish uses rok for year, but the plural is lata — literally “summers” — which is why someone’s age is given in summers. Old records lean on this constantly, and it is a small window onto a time when a year was counted by the season that mattered.
