Logical question: How exactly do you expect a society created by Japanese to be aware of Roman culture and calendars? All English names for the months are based on Latin, which does not exist in Underworld. Instead, Underworld follows the modern Japanese system: all months are named after their number. The first month is literally called the first month rather than "January", the second month - the second rather than "February" etc.. Because of this, there really isn't any difference between how the months are called in Japan and Underworld. While the anime subs and Yen Press decided to just translate the months as if the story was still taking place in Japan, the wiki decided that it doesn't make sense for Underworld people to actually know anything about Roman month names and thus decided to use literal translations for the month names in Underworld.
