brake time, sidebar callendar formating and localization problem

I have set brake time, but it would not work.

Because of sidebar background being black, it is hard to see an inscription of a weekday. Is it possible to solve the problem without changing the theme itself?

In the sidebar the date is shown incorrectly, that being the genitive case of month name instead of correct nominative case in lithuanian.

Could you create a pagination for sidebar callendar?
