Dayson

Meaning & origin

Dayson is a modern American coinage that first entered U.S. birth records in 1983. It saw its peak popularity in 2015, when the highest number of babies received the name, but has been on a downward trajectory since 2016, dropping to a rank of 4,249 in 2025. The name's rarity means that any given Dayson is statistically one of only about 14 boys nationwide in a typical recent year. The name follows the contemporary pattern of creating surnames or compound names ending in son, similar to its cousins Jayden, Brayden, and Mason. Despite its synthetic origins, Dayson has a straightforward phonetic appeal and is most commonly found in the United States.

Dayson appears to be a modern invented name, formed by combining the common name element Day (from the English word for the period of light, or as a surname derived from the given name David) with the popular suffix son. It first appeared in U.S. records in 1983 and saw a modest peak in 2015, but its usage has since declined. The name has no historical roots beyond the late 20th century.
