About Stardates

Stardates are a fictional time measurement system used in the Star Trek universe. This calculator converts Earth dates to stardate format using two different epochs:

Space Age (1957): Based on the beginning of the space age with Sputnik's launch
Star Trek (2323): Based on the Star Trek universe timeline

The calculation uses a formula where each Earth year equals 1000 stardate units, with fractional days calculated proportionally.
