The ancient Greeks had two words for time. The first was chronos. The second was kairos. The Greek god Chronos was imagined as an elderly, grey-haired man, and his name connotes the literal ticking clock, the chronological time, the kind we measure (and race about trying to use efficiently). Kairos is different. While it is difficult to translate precisely, it refers to time that is opportune, right, different. Chronos is quantitative; kairos is qualitative. The latter is experienced only when we are fully in the moment - when we exist in the now.
