For Kirk’s birth date in Julian system figure would be in millions. For conventional dating suggest 3235 to 3271. (, Scene 175) C-1277.1 to 1313.7 – We presume dates are in days, Kirk would only be 36 days old. A Julian cycle is 7,980 years, and the Julian day measurement would be scientifically authentic.
