There are seven common ways of stating dates that are used for ancient times.
Many ancient writers tried to establish the dates of events by cross referencing several local references, such as "the days of Uzziah in Judah and Jeroboam in Israel". The Greeks created one answer to the problem of each town having their own calendar and date of the new year with the Olympiad system, which, with variances in dates of the game, and local new-years, allows confidence in dating to within 18 months. The historian Eusebius ties dates in several systems together with entries cross-dated, viz "in the 18th Year of Xerxes in Persia, the first year of the 78th Olympiad, and the 1549th of Abraham" (Xerxes 18 = Ol 78.1 and 1549 AA). The Astrologer/astronomer Ptolemy of Alexandria compiled a cross reference of rulers and astronomical events, commonly called the Canon, which is one of the main sources of dates for this table of epochs.
Of our sources, one with a strong reputation for honest scholarship is Livius, which we can strongly recomend for further reading on many of the events in these timelines.
This site uses AM, which avoids dealing with any dates "Before Zero" within the span of recorded history, and makes math simple.
Dates and events are Israel-centric - The empires that sought to eliminate the Jews and their bothersome strict monotheism are dead history, Israel and the Hebrew language survive.
