names of months

Hi
Where (maybe language file?) can I find the names of months for I could change names into Polish. In sidebar the names of months are still in English (short) I cannot find the language file to translate it.

Best regards for all, January

Dear January.
Thanks you for using product our.
I'm sorry. You can give me your site or a image where you want translate "month" for me.
I don't know where you want change names.

Dear Huyen

My website is www.krasnik.eu , and when you open it you will see EventOn module in the middle of the site. As now you can see in Sidebar the names of months are in English (short) and I would like to change them into Polish. The second problem is that days of the week in Event module are in English also and time format is English, not Polish. And the last thing if I use Weather module the numbers in mini Calendar changes into white so they invisible on the website if I turn this module offf everything is OK. Can you help me please?
Best for you, January

It there anybody there who can halp me? Almost 3 days without reply? Unheard...very pity...

Hi January.
I'm sorry for reply later.
Because I still don't find the solution for you. Please give me some time.
But I saw in your site, some language translated month. Because Date, month of events module will translate when you install other language.
Please give me your account of administrator via private message. I will try to check it again
Thanks for your empathy
