Wrong translation of the months

[rzuhovski0]

I've noticed that when using calendar on device with no english language selected, the months get translated correctly, however, they are wrongly declensionised.

In English, declension is not a thing = It is January -> It will happen in January (the word January is the same)

But in other languages, it is pretty common to slightly alter the words depending on the context, for example in Slovak :

It is Januar -> It will happen in Januari (extra i at the end)

The translations of the months are like the example above. Instead of Januar, Januari is displayed, which does not make sense.

I suspect that is an Android issue, however, if anyone fixed this, please let me know.
