Special Relativity: Time Dilation Calculator

Calculates how time passes differently for observers in relative motion using Δt' = Δt / √(1 - v²/c²).

Inputs

Enter the speed of the moving observer relative to the stationary observer. Must be less than 100% c.

2. Which time interval do you know?

Time measured by the moving observer (e.g., on the spaceship).
