We analyze K0 - K̄0 oscillations in space in terms of propagating wave packets with coherent KS and KL components. The oscillation probabilities PK0→K0(x) and PK0→K̄0(x) depending only on the distance x, are defined through the time integration of a current density j(x,t). The definition is such that it coincides with the experimental setting, thus avoiding some ambiguities and clarifying some controversies that have been discussed recently.
