"Mâine este sâmbătă."

Translation: Tomorrow is Saturday.

[MotherEffi]

Like in the other Romance languages

[Wzburzony]

And similar to slavic languages, for example "sobota" in Polish or "суббота" in Russian

[Lng52-._]

Are days of the week and months supposed to be capitalized?

[potestasity]

Nope.

[vincemat]

It actually IS Saturday tomorrow O_O
