Symbol: Δτ
Definition: duration indicated by a clock

Note 1 to entry: The proper duration ΔτAB is the shortest of the durations ΔtAB in all frames S′ and for inertial frames, ΔτAB=ΔtAB/γ.

Note 2 to entry: For events A and B separated by an infinitesimally small squared space-time interval, the proper duration ΔτAB is the shortest of the durations ΔtAB in all frames S′ and ΔτAB=ΔtAB/γ.

Note 3 to entry: The proper duration is a Lorentz invariant.

Note 4 to entry: The coherent SI unit of proper duration is second, s.
