The Modified Julian Day (MJD) system was established as a new timekeeping method in the context of astronomy and timekeeping. This adjustment was made by the astronomical community to provide a convenient and universal standard for tracking the passage of days. It simplified calculations related to time intervals and astronomical events. MJD counts days from a base date of November 17, 1858, making it easier to compare data from different eras and locations in celestial observations.
