What Does AJD Stand For?

AJD stands for Astronomical Julian Day

AJD, or Astronomical Julian Day, is a continuous count of days that serves as a standardized measure of time in astronomy. It begins at noon on January 1, 4713 BCE in the Julian calendar and allows astronomers to easily calculate time intervals between astronomical events. The AJD system is particularly useful in tracking celestial events and observations, providing a uniform framework for comparing data across different epochs.
