This calculator requires the use of Javascript enabled and capable browsers. This creates and displays the purely hypothetical stardate time in Intergalactic format, per the very loose guidelines of Star Trek. This pseudo-standard time system, though working and clock based on UTC time, has no secure factual basis or foundation. This is the same time format as in my 1979 TRS-80 Model 1 (Z80 based), Star Trek game. The actual UTC time is displayed for comparison.
