"Kwiecień to miesiąc."

Translation: April is a month.

[MrOolong]

When are the months introduced before this?

[foo__bar]

You learn them in this lesson.

[DeltaCrunch]

when do you use jest rather than to? Why would the sentence not read "Kwiecień jest miesiąc."

[tczek]

Kwiecień jest miesiącem.

[MythicalEspeon]

Difference between jest and to? Is it because April is like a proper noun? Or do proper nouns not exist in Polish?

[chciplycar]

That's so confusing, because "Květen" means May in Czech :D
