Wit's name day is celebrated on June 15 in Poland.
The first name "Wit" is seldom encountered as a formal given name in the USA, often functioning more as a nickname derived from its core meaning of sharp intelligence. Its origin is directly linked to this English word describing mental agility and verbal cleverness. The name carries a distinctly 'techy' and energetic mood, suggesting quickness and confidence. Gender classification for "Wit" is generally considered fluid or unisex due to its abstract source. It stands out due to its brevity and direct association with intellect rather than traditional naming customs.
