For people wondering, this user's name is zout which is Dutch for salt. Now this could be a coincidence or the user might actually be Dutch speaking themselves, even Belgian perchance?
I'm Dutch, not Belgian. I was also referring to "jannewarie" as the phonetic spelling of "januari", which is placed over parts of Belgium, the Netherlands and Germany. Looks like I made an unintentional joke!
Yeah that's weird, it's the Limburgs version of January. But it's weird to include a local dialect instead of only primary languages. And if Limburgs is included, why not Frysk as well?
It appears that there's not anything on Belgium actually, probably because the wallons use the french word and I assume the flemings use the dutch word
Belgium has "jannewarie" for the Flemish part, and "djanvi" for the Wallon part (I could have been more clear on that). It seems this map mixes official language spellings with phonetic dialect spellings.
