Compare calculators
Both calculators run independently — change the inputs on either side to compare results.
Relativity
Time Dilation Calculator (Velocity)
Calculates the dilated (coordinate) time experienced by a stationary observer when a moving clock ticks off a given proper time at relativistic speeds. Essential for understanding special relativity and GPS corrections.

Relativity
Gravitational Time Dilation Calculator
Calculates how gravity slows time near massive objects using Einstein's general relativity. Use it when comparing elapsed time at different distances from a planet, star, or black hole.
