Wit's name day is celebrated on June 15 in Poland.
Wit is an uncommon first name in the USA, evoking a sense of intelligence and quickness of thought, reflecting its English meaning of "cleverness" or "humor." Its origin is firmly rooted in the English language itself, used historically as a descriptor before becoming a given name. The mood of the name Wit is decidedly sharp and playful, suggesting someone bright and perhaps a little mischievous. While not strongly gendered, it leans more masculine due to its association with intellectual prowess. This name carries an elegant yet accessible tone, uncommon enough to be memorable.
