Note: If anybody needs to use the danish language files, then you need to rename the language files to the-events-calendar-da_DK.po and the-events-calendar-da_DK.mo
The files included in the plugin is named the-events-calendar-da_DA.po and the-events-calendar-da_DA.po and therefore they are not working since the WP-lang for Denmark is da_DK
Just a tip
