Finnish for busy people

The Months – Kuukaudet

This article has a very narrow focus; it only deals with the months of the year. If you’ve just started learning Finnish, you should focus on part 1 and 2 of this page and postpone learning the other expressions until a little later.

If you’ve advanced far enough, you may also want to learn more about other expressions of time, you can do so on our overview page of expressions of time. You should also check out our page on questions of time (e.g. Kuinka kauan? Mihin mennessä? Moneltako?). We also have separate pages about telling the time, the days of the week and the years.

1. January – In January

Below, you can find both the basic form of the months and the inessive form (-ssa), which is used to express that something happens in or during a month. Notice in the table below that the months do not start with a capital letter in Finnish!

Finnish English Finnish English
tammikuu January tammikuussa in January
helmikuu February helmikuussa in February
maaliskuu March maaliskuussa in March
huhtikuu April huhtikuussa in April
toukokuu May toukokuussa in May
kesäkuu June kesäkuussa in June
heinäkuu July heinäkuussa in July
elokuu August elokuussa in August
syyskuu September syyskuussa in September
lokakuu October lokakuussa in October
marraskuu November marraskuussa in November
joulukuu December joulukuussa in December

Most of the names of the months actually mean something in Finnish. Some of the words that these months are based on aren’t used at all anymore in present-day Finnish, but other are still clearly recognizable. For example, kesäkuu literally means “summer moon” and joulukuu means “christmas moon”.

2. From January – Until January

If you want to express a timespan by saying during which month something began and when it ended, you can use the elative (-sta) and the illative (mihin) for this purpose. This way, you can express, for example, that you’re working from January until June (Olen töissä tammikuusta kesäkuuhun).

Finnish English Finnish English
tammikuusta from January tammikuuhun until January
helmikuusta from February helmikuuhun until February
maaliskuusta from March maaliskuuhun until March
huhtikuusta from April huhtikuuhun until April
toukokuusta from May toukokuuhun until May
kesäkuusta from June kesäkuuhun until June
heinäkuusta from July heinäkuuhun until July
elokuusta from August elokuuhun until August
syyskuusta from September syyskuuhun until September
lokakuusta from October lokakuuhun until October
marraskuusta from November marraskuuhun until November
joulukuusta from December joulukuuhun until December

3. Using Adverbs: Starting from January

In addition to being able to express between which months something takes place, we can use the forms above also in combination with certain adverbs. The words lähtien and alkaen can be used to express the starting month of the action, in combination with the mistä-form. Likewise, the word asti can be used to express the last month of the period, in combination with the mihin-form. Lastly, you can use the word mennessä to express by when (by what month) something has to be finished.

Finnish English
Olen lomalla kesäkuusta alkaen
I’m on vacation starting from June.
Tammikuusta alkaen työvuorot pitenevät.
Starting from January shifts will get longer.
Maaliskuusta lähtien työskentelen osa-aikaisena. I’m working half-time starting from March.
Elokuusta lähtien bussit kulkee harvemmin.
Starting from August the buses ride more rarely.
Olen lomalla syyskuuhun asti. I’m on vacation until September.
Aurinko paistaa lokakuuhun asti. The sun will shine until October.
Maksa laina takaisin elokuuhun mennessä! Pay the loan back by August!
Joulukuuhun mennessä tiedetään vastaukset. By December we will know the answers.

4. Kuussa: Last Month – Next month

It is often also useful to be able to express that something will take place next month. For these kind of sentences, we use “tässä kuussa”, “viime kuussa” and “ensi kuussa”. Please note that it is not viime kuukausi or viime kuukaudessa. Learners of Finnish make a lot of mistakes with this.

The form “kuussa” is also used to say how often (how many times) something happens during a month (once a month, twice a month, etc).

Finnish English
Missä kuussa talvi alkaa?
During what month does winter start?
Matkustin viime kuussa Tallinnaan.
I traveled to Tallinn last month.
Muutan ensi kuussa Helsinkiin. I’m moving to Helsinki next month.
Tässä kuussa on 28 päivää.
In this month there are 28 days.
Käyn siskoni luona kerran kuussa.
I visit my sister once a month.
Käyn isän haudalla kaksi kertaa kuussa.
I visit my father’s grave two times a month.
Näen painajaisia suunnilleen kolme kertaa kuussa.
I have nightmares about three times a month.

5. Kuukausi Sitten – Kuukauden Päästä

Next, let’s take a look at how to express that something happened a month ago or will happen a month from now. Both of these constructions are very different from each other.

Sitten” refers to the past, and will be located behind the time span in the sentence. When something happened a month ago, you will say “kuukausi sitten”. Please be careful to avoid saying “yksi kuukausi sitten”, because the “yksi” is clear from the form already. For two, three, four months, you will use the partitive, because that’s the form you use after a number.

Päästä” and “kuluttua” refer to the future and will also be located behind the time span in the sentence. However, these two words are postpositions (look at 2.3. on that page), which means that the time span will be inflected in the genitive case. Again, avoid using “yksi” when saying “kuukauden päästä” or “kuukauden kuluttua”. When you’re using a larger number, you will have to inflect that number in the genitive with these two postpoisitions.

Finnish English
Synnytin vauvani kuukausi sitten. I gave birth to our baby a month ago.
Aloitin kurssin kaksi kuukautta sitten. I started the course two months ago.
Vauvani syntyy kuukauden päästä. My baby will be born in a month.
Kurssini alkaa kahden kuukauden päästä. My course starts in two months’ time.
Kuukauden kuluttua järvissä voi taas uida. A month from now you can swim in the lakes again.
Kolmen kuukauden kuluttua syksy alkaa taas. In three months’ time autumn will start again.

Can Asti be used as Since, if the sentence is in perfect tense. for example olen ollut lomalla kesäkuusta asti



How to say “in the last months”? I saw “viime kuukausina” and it indeed seems to be used quite frequently. I’m not sure why the essive case is used here, it’s not used with months otherwise. The same with “viime viikkoina”.

Inge (admin)

For the plural, “viime kuukausina” is the only option (while the singular is “viime kuussa“). With viime, you just “have to know”. There’s no reason I know of that accounts for the difference. Note how the seasons, eg. “kesällä” also turns into “viime kesänä“.

I hadn’t actually come across “viime viikkoina” before! The funny thing is that if you google the combination (“viime viikoilla” “viime viikkoina”) you actually get quite many search results where both are used in the same source. My intuition would have assumed “viime viikoilla” would be more common, but that doesn’t seem to be the case. I’m as surprised as you are!

Again, you’ll just have to remember them on a case-by-case basis.
