Golarion Timeline / Overview
Age of Darkness
Timeline : -5300 AR to -4500 AR
The Age of Darkness was a thousand year period in which the sun was blocked by ash knocked into the atmosphere by Earthfall in -5293 AR and ending in -4294. During this age the Orcs emerged from their subterranean homeland fleeing the Dwarves who later also took their first footsteps on the surface world  The blocking of the sun allowed Zon-Kuthon to return to Golarion and claim an item from the First Vault due to a deal made with Abadar. See Category:Age of Darkness for a complete list of year articles within the Age of Darkness.
Age of Anguish
Timeline : -4500 AR to -3500 AR
The Age of Anguish was a roughly eight hundred year period originating in -4294 AR when the skies finally cleared of the dust from the Earthfall. This age is characterized by the conflicts of primitive peoples in a desperate struggle for survival and domination in a world left shattered by the Age of Darkness. The end of the Age of Anguish was marked by the founding of the Osirion civilization in circa -3472 AR. 
Age of Destiny
Timeline : -3500 AR to -1 AR
The Age of Destiny began circa -3470 AR with the founding of the Osiriani civilization and spanned three and half millennia until the founding of the great city of Absalom. The rise and fall of Osirion was witnessed at the early period of the Age of Destiny, though many other civilizations were to rise after Osirion fell into decline. Notable mentions include the founding of Taldor by the descendants of Lost Azlant and of the Lands of the Linnorm Kings. Wars during this age include the Nex-Geb War and the tarrasque invasion of -632 AR.
Age of Enthronement
Timeline : 1 AR to 4605 AR
The Age of Enthronement began with the founding of Absalom and it’s inception is also the starting point for the Absalom Reckoning dating system. The Age of Enthronement spans the years from 1 AR until 4606 AR when Aroden, the god of humanity, died. This age is characterised by the emergence of a number of gods who ascend to divinity through the Test of the Starstone. Gods to survive the test are Aroden in 1 AR, Norgorber in 1983, Cayden Cailean in 2765 and Iomedae in 3832. The nations of Andoran and Cheliax were founded as expansion from the kingdom of Taldor. The Oath Wars raged across northwest Garund between 2498 AR and 2560 as the churches of Nethys, Norgorber and Sarenrae vied for dominance. The Whispering Tyrant arose in 3203 AR invoking the Shining Crusade in 3754 AR which burned for three quarters of a century and ended with the founding of Lastwall to defend against the return of the lich king. In 4305 AR Cheliax began an extended period of expansion annexing lands in Molthune and Varisia which would become known as the Everwar.
Age of Lost Omens
Timeline : 4606 AR to present
Golarion is now in what is being called the Age of Lost Omens. It began in 4606 AR with the death of the god Aroden and continues to the present1. Aroden himself had prophesied thousands of years ago that he would return on the cusp of mankind’s greatest triumph. His priests and followers calculated the supposed exact time of this event and prepared for it with lavish pomp. On the prophesied date, instead of his return all contact to the god was lost and the world was devastated by terrible storms and other calamities. Since then no major prophecy has come true.
