Kairos

concept
Καιρός
The opportune moment

Kairos was the concept of the perfect, fleeting moment of opportunity — distinct from chronos (sequential time), kairos is the critical instant that must be seized.

The Myth

The Greeks had two words for time: Chronos (sequential, measured time) and Kairos (the right or opportune moment). Kairos was personified as a young man with a forelock but bald behind — you could seize him as he approached but not after he passed. The concept was central to rhetoric (when to speak), warfare (when to attack), and medicine (when to intervene). Hippocrates wrote: "Time is that wherein there is opportunity, and opportunity is that wherein there is not much time."
