I have a listing page for articles that includes the date, converted into a long date string ("Friday, December 21 2018"). On all of my lower environments it is showing the dates in English but on prod it is showing the date in German.
date.Text = item.Date.ToLongDateString();
The site doesn't even use German as a language, just English and French. The listing page and all story items are English. I figure this must be an environmental Sitecore issue, since it shows in English on all lower environments. What could be causing this, and can I fix it without a code change?
