Kairos

Kairos is an ancient Greek word meaning the "right or opportune moment". It is now used in theology to describe the qualitative form of time. In rhetoric kairos is "a passing instant when an opening appears which must be driven through with force if success is to be achieved." (E. C. White, Kaironomia p. 13)
