Julian Day is an astronomical method of measuring time, the number of days from noon on January 1, 4713 BC (4712 BC according to the astronomical count of years) according to the Julian calendar.
Julian Day was first proposed by English astronomer John Herschel in 1849. 4713 BC is the beginning year of the Julian period, introduced by Joseph Scaliger in 1583 for the purposes of history and chronology.
Herschel chose noon on the meridian of Alexandria as the beginning of the day, since this was how the days were counted in the classical Almagest of Claudius Ptolemy.
