Kairos

Meaning & origin

Kairos is a rare masculine name that entered American records in 2008, reflecting a modern interest in Greek philosophical terms. As of 2025, it ranks 1347th, with an incidence of about 1 in 12,201 births. Its popularity has been rising since 2009, reaching a peak in 2025. The name is most commonly given in Massachusetts, Georgia, and Virginia, suggesting an appeal among parents seeking a distinctive, intellectual name with classical roots. Its etymology ties it to the Greek concept of the opportune moment, a notion valued in rhetoric and theology. While still uncommon, Kairos fits a pattern of ancient Greek names revived for their distinctive sound and cultural cachet, often paired with sibling names like Athena and Apollo.

Kairos comes from the Ancient Greek word καιρός (kairos), meaning 'the right, critical, or opportune moment.' In classical rhetoric, it denoted the opportune time to speak or act, distinct from chronos (sequential time). The name entered English usage as a philosophical concept and was adopted as a rare given name in the late 20th century, particularly in the United States.
