Kairos

Kairos (Ancient Greek: καιρός) is an ancient Greek word meaning 'the right, critical, or opportune moment'. In modern Greek, kairos also means 'weather' or 'time'.

It is one of two words that the ancient Greeks had for 'time'; the other being chronos (χρόνος). Whereas the latter refers to chronological or sequential time, kairos signifies a proper or opportune time for action. In this sense, while chronos is quantitative, kairos has a qualitative, permanent nature.The plural, kairoi (καιροί) means 'the times'. Kairos is a term, idea, and practice that has been applied in several fields including classical rhetoric, modern rhetoric, digital media, Christian theology, and science.
