This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
Calendar Base supports localization using the same configuration as TYPO3 and other extensions. The most critical and often missed step in this location is to set the appropriate locale in Typoscript. This locale information is used to generate day and month names in the correct language.
- Open http://www.YOUR-SITE-URL.com/typo3conf/ext/cal/misc/locales.php in your browser. This will show you a listing of all the locales available on your system. Copy the the one that best matches your language and/or location.
- Within the Typoscript Setup for your page, add
config.locale_all = MY_LOCALE
where MY_LOCALE is the value you copied in step 1.
- View the Frontend Calendar pages. Day and month names should now be shown in the correct language.
