Translate untranslated words in Drupal I'm using calendar module and I noticed when browsing web that some words are not translated (e.g. "prev," "next," "day," "week," "month," "year"). Is it possible to write somewhere the translation for these words?
Content Translation module can help us using Translation Interface (example.com/admin/config/regional/translate/translate) in this regard to search the string and then define a translation against appropriate language.

The strings can only be translated if they are not hard coded and used with t() function.

t() always searches for appropriate translation with respect to currently selected language otherwise it returns the original string.
