What is "kayvan"

Kayvan (also spelled Keyvan, Kayvon, Keivan, Keywan, or Kaevon, ) is a Persian masculine given name, also occasionally a surname, meaning Saturn. It is related to the word for Saturn in several old languages, including "Kaimanu" in Sumerian, "Kayamanu" in Akkadian, "Kion" in Syriac, and "Kewan" in Pahlavi. That a 16th-century high priest of Estakhr was named Azar Kayvan suggests that "Kayvan" was used as a name for a person in Iran as early as that time, at least among Zoroastrians. "Kayvan" is distinct from the similar Persian word "Kayhan", meaning "universe", also used as a masculine given name. To English speakers, the spelling Kayvon is closest to the Persian pronunciation, .

"Saturday", the day of Saturn, finds its Classical Persian equivalent in "Keyvansheed".
