Time Dilation Formula / Calculator


Use our time dilation formula calculator to explore relativistic travel times, observer vs. traveler time, and velocity as you near the speed of light.

You'll discover the differences between traveler and observer times, maximum velocity, energy requirements, Doppler shift effects, Lorentz factor changes, and how distances vary between reference frames. Time actually passes slightly faster at the top of a tall building compared to ground level. This isn't science fiction - it's a real effect that scientists have measured using super-accurate atomic clocks.
