History & Origin

Moon is the English word itself, from Old English mona — a root shared across Germanic languages and distantly related to 'month', since the moon was humanity's first calendar. As a given name it surfaced in the counterculture era (Moon Unit Zappa, 1967) and returned with the celestial-name wave that made Luna a top-ten staple.

It also exists as a Korean surname and a Burmese name element, giving it quiet international reach. As an American first name it remains very rare — for parents who find Luna lovely but too popular by half.

Did you know? Frank Zappa named his daughter Moon Unit in 1967 — and she grew up to voice the era-defining 'Valley Girl' on her father's 1982 hit.
