Language problem

Hello,

I have a problem with the language. Im displaying a one day callendar using the shortcode. The navigation dates (previous and next day) are in my language (to which WordPress is set – czech (cs), but the actual selected date, the month in paritcular, is in English. How do I fix this so all of it is czech? My page is at paneboze3.xf.cz .

Additionaly, I would like to restyle the callendar a bit – for starters, I dont want to show the date on every entry, since all entries are for one day which is displayed at the top. Also – it would be very helpful if I could do it so it has a fixed height *and* last thing – is it possible to view events in two collumns? One for before mid-day, one for after mid-day? Thanks for help!
