Claudius Ptolemy
Censorinus wrote that an Egyptian New Year fell on July 20, 139 AD according to the Julian Calendar handed down to us. Therefore, when historical manuscripts, relics and artifacts using Egyptian dates are discovered, the equivalent Julian date can easily be determined.
Claudius Ptolemy used the Egyptian Calendar when dating the reigns of kings. Ptolemy's Cannon of Kings listed kings dating as far back as the first year of the Babylonian ruler, Nabonassar, which was Feb 26 (Thoth 1 by Egyptian reckoning.), 747 BC.

Dating Systems
Regnal Years
Egyptians reckoned days from dawn to dawn and used the non-accession-year method for dating kings. When a king died and a new king took the throne, that year was counted as the last year of his reign and the first year of the new king. Other calendars, like the Babylonian, Persian and Hebrew calendars, used the accession-year method for dating and would have considered that year to have been the accession year of the new king. His first year would not have begun until New Year's Day.
The non-accession-year method did not fit as neatly on a number line as the accession-year method, but when one recognized that such a dating system was used, then reckoning wasn't really so difficult. Throughout history, Judah generally used accession years, while Israel sometimes used the accession year system (postdating) and sometimes used non accesion (antedating) reckoning of time.
The small white dot near Earth in our solar illustration is a lunar apside (perigee or apogee). The red dot is a node of the ecliptic (ascending or descending). When a new or full moon is at or is opposite to the red dot, an eclipse occurs.
