+# Proper name and translation
+
+## Given name gender
+
+As a tradition, ancient Gaidaanan people gave names to newborns based with
+gender based on the month of the year, as did people during the story
+timeline.  This is obvious with Hàäsdáïga month names, but it is not that
+transparent to use in our world, which use 12 months in both solar and lunar
+calendar (I am not aware of any other calendar system).  For that reason, I
+propose that we instead decide based on lunar months:
+
+- Wood if the person is born from month 1-3
+- Fire if the person is born from month 4-6
+- Metal if the person is born from month 7-9
+- Water if the person is born from month 10-12
+
+This corresponds to the four seasons.  Optionally, people born in month 6 or 7
+can be assigned gender Earth.
+
+## Family name gender
+
+Family names usually have meaning.  If it is a noun (e.g. Poisson, Rice, Wood,
+Pierre, Lagrange, ...) or adjective (Legrand, Leblanc, Weiss), they carry the
+same gender as that corresponding noun or verb, even if it is not translated.
+If it is a profession, which does not have a default gender, it would
+theoretically be the gender of the first person carrying that name.  That is
+however not feasible, so instead it is associated with the thing that
+profession works on.  For example, Smith → metal, Gärtner → wood.  For names of
+unknown origin (Johnson, James, Nguyễn), just choose the first vowel in the
+name for gender.
+
+All family names in Hàäsdáïga are nouns, though most people don't use it.
