You first need to know that Stardates in Star Trek start at the basedate. The basedate is January 1, 2323 (Stardate 0). Stardate units standardize time measurement between various cultures, worlds and races. It has little relationship to Earth's time as we know it; one hour aboard a starship at different impulse speeds may equal many Earth hours. Stardates are calculated through a complicated equation that takes into account relativistic effects, universal expansion and the effects of gravity on time and space. Every so often the stardate system has to be updated to take into account the expansion of space or other natural effects. Starfleet vessels did this by contacting a nearby Starfleet time beacon and adjusting their internal chronometer.
