Hi rasitozdemir,
This date is a system current date and translated automatically according to the locale settings on the system that PHP is running. Month and weekday names and other language-dependent strings respect the current locale. That is work if the respective locale installed in your system.
By the way, in the nearest future we planned to release new plugin version with 2nd theme. This release will have a lot of changes and includes global changes in the language files. So if you try to add custom translation for your language (that currently is not supported by our plugin) based on existed .po files, you possible will have issues with plugin after update.
As suggestion, if you will need to add specific language we can send you necessary files with full list of variables for translations and then integrate it to our plugin.
If it is suitable for you please send request to support@webcodin.com.
With kind regards,
WebCodin WordPress Team
