Of course, I believe that everyone uses their own native language as much as possible.
So as you said, the translation function is beyond the plugin. At least I don’t need translation function.
However, I use Chinese, and the RSS feed is completely Chinese. At this time, I checked the date display function and found that it displays the year and date in Arabic numerals, but it displays the month in English words.
So I think there may be something wrong with this.
That’s why I suggested that using Arabic numerals. This may be an easier solution to adapt to different languages.
