History & Origin
Dat is a Vietnamese personal name meaning 'achievement' or 'attainment.' It entered United States records notably after 1979, as Vietnamese refugees and their families settled in America and passed on traditional given names.
It has always been rare in national data, given to only a couple dozen boys a year at its early-1980s high within the Vietnamese American community. It reads clearly as a heritage name rather than a mainstream American pick.
