The Julian Date (JD) represents the count of days and fractions of a day since noon on January 1, 4713 BC at Greenwich. In contrast, the Modified Julian Date (MJD) adjusts this by an offset of 2,400,000.5 days, beginning at midnight on November 17, 1858. The Julian Date system is frequently employed in scientific time measurement, particularly within the astronomy community, as it facilitates a unified framework for diverse calendar systems.
