Meaning & origin
Dayon is a modern American coinage that first appeared on the U.S. baby name charts in 1975. It reached its peak rank of 8,243 in 2000, after which it entered a steady decline. In 2025, the name's one-in-189,786 incidence underscores its rarity. The name fits a pattern of invented names combining the Da- prefix with familiar endings like -on or -an, similar to Dajon or Davon. Its usage has never concentrated in any particular state, reflecting a scattered but persistent presence across the country over the past five decades.
Dayon appears to be a modern coinage, likely formed by blending the popular prefix Da- (as in Dajon, Davon) with the name Leon, or as a respelling of Dayan, a Hebrew name meaning 'judge'. It emerged in the United States in the late 20th century, first recorded in 1975, and saw peak usage during the 2000s. Its usage has since declined.
