Days of the week (-na, -nä)

Days of the week

Just like the months, the days of the week in Finnish are not capitalized unless they appear at the beginning of a sentence. You will also notice that five of the seven days end in -tai.

Monday
maanantai

Expressing "on" a day (-na / -nä)

To say that an activity happens on a particular day, Finnish uses a form called the essive case. You create this by attaching the ending -na or -nä directly to the name of the day.

Because all seven days of the week contain back vowels (a, o, or u), vowel harmony rules dictate that every day of the week takes the exact same back-vowel ending: -na.

I am meeting you on Monday.
Tapaan sinut maanantaina.
We clean the kitchen on Tuesday.
Me siivoamme keittiön tiistaina.
I wake up early on Wednesday.
Herään aikaisin keskiviikkona.
We will be in the sauna on Thursday.
Me olemme saunassa torstaina.
We drink wine on Friday.
Me juomme viiniä perjantaina.
She is baking a cake on Saturday.
Hän leipoo kakun lauantaina.
We rest on Sunday.
Me lepäämme sunnuntaina.
