From A Wiki of Ice and Fire
Year 129 After the Conquest (129 AC) is a year in the Westerosi calendar, the 129th after Aegon's crowning in Oldtown that maesters and educated people use as a reference to date the years.
129 AC was marked by the death of King Viserys I Targaryen, which was immediately followed by the beginning of the civil war known as the Dance of the Dragons, where both Prince Aegon Targaryen and Princess Rhaenyra Targaryen claimed their fathers crown. The war knew many deaths, and lasted from the death of King Viserys, on the third day of the third month of 129 AC, until halfway in 131 AC.
