You install the English version of WordPress. You publish pages and articles in another language. You install Events Calendar 6.7.1. The calendar widget is in English. You want the calendar widget to match the language of pages and articles.
You would think, that there would be a language option in the Events Calendar section of panel. No. That's not the case. That would be too smart!
You then get a cup of coffee and go through the PHP files of the Events Calendar and find language files from all parts of the World. Yay! You would then think, that one of these languages could be selected in a configuration file. No. That's not possible. That would be too smart!
You would then think, that you could modify the English language file. No. That's not possible. There is no English file! That would really be too smart! In stead, it seems to be a result of a language compilation system - without the compiler. Of course, a simple makefile solution would be too smart also.
You would then think, that you could use your rusty programming skills and do a quick and dirty translation in the PHP files of Events Calendar. No. That's not the case either. That would be too easy. The language settings seems to be called from a dark hole within WordPress or PHP core system.
It remains a mystery and a waste of time so far.
Dear author and experts, what is the procedure to change the Events Calendar widget from English to another language than WordPress?
