Kairos and Chronos are two Greek concepts of time.

Chronos refers to chronological or linear time, while kairos refers to a moment of indeterminate time in which something special happens.

Kairos time is often associated with opportunity or the right moment to take action.

Chronos time is more objective and measurable.
