Only one ex-consul known (Cicero), out of nearly 100 known names

42 BC:

January 1: Julius Caesar is proclaimed a god (due to a comet that appeared at games in his honor in 44); Octavian becomes "son of a god", divi filius
Spring - Winter Preparations for the campaign against the forces of Brutus and Cassius, the 'Liberators'
October 23: Antony and Octavian avenge Caesar's assassination at the Battle of Philippi (well, Antony does all the work).

41/40 BC: War of Perusia between Octavian and Antony's brother and wife, Lucius Antonius and Fulvia. Octavian wins.

40 BC: Treaty of Brundisium between the Triumvirs: Octavian gets the West, Antony the East, Lepidus Africa.  Antony marries Octavian's full-sister Octavia to seal the deal.

39 BC: Treaty of Tarentum: Antony and Octavian cede Sicily, Sardinia and Corsica to Sextus Pompey as a "Protectorate." Octavian marries Scribonia, a relative of Sextus Pompey, with whom he has one daughter, Julia.

38 BC: Octavian fights two indecisive sea battles with Sextus Pompey and loses his fleets in storms; divorces Scribonia upon the birth of Julia and marries Livia. The Triumvirate's mandate runs out.

37 BC: Triumvirate renewed for 5 more years. Agrippa trains a new fleet near Naples. Antony marries Cleopatra (this is invalid in Rome) and starts his disastrous Parthian Campaign.

36 BC: Octavian, with the help of Agrippa and Lepidus, defeats Sextus Pompey at Naulochus in Sicily; Lepidus attempts to take over Sicily, but instead loses his position as Triumvir, his army and his navy and is sent into exile. Octavian now has more military resources than Antony. East and West are now in complete control of two men.

34 BC: Antony breaks with Rome and Octavian for good. He holds a "triumph" in Alexandria to celebrate his "victory" in Armenia. Officially divorces Octavian's sister Octavia. Donations of Alexandria: Antony divides much of Rome's eastern empire among Cleopatra's children (3 of whom are his as well) and declares Octavian a usurper of Caesar's rightful heir, Caesarion, son of Caesar and Cleopatra.

33 BC: Triumvirate runs out again; Octavian campaigning in Illyria

32 BC: The "war of words" between Antony and Octavian; Octavian reads Antony's will (which again declares Caesarion as Caesar's lawful heir) in the Senate. The west, alarmed at Antony's apparent prediliction for the East and willingness to advance the interests of Cleopatra over Rome's, officially declares war on Egypt and demands Octavian (who currently holds no magisterial office) as "Dux" or leader of the war effort.

31 BC, September 2: Octavian (now consul for the third time) and Agrippa are victorious over Antony and Cleopatra at Actium.

30 BC, August: Octavian and his forces take Alexandria; Antony and Cleopatra commit suicide.

29 BC, August 13-15: Octavian celebrates a triple triumph at Rome (Illyria, Actium and Alexandria) on three successive days; he attributes the success to Apollo. The influx of money and booty causes a sharp decreas in interest rates, making Octavian more popular than ever.

28 BC: Octavian dedicates a temple to Apollo on the Palatine Hill, Rome (next to his home).

27 BC, January 13 & 16: Octavian "hands the Republic back to the people" and in return receives the title Augustus and an enormous proconsular province including Spain, Gaul, Syria and Egypt. He thus controls most of the military provinces, and hence maintains his preeminent power. His virtues are commemorated in golden shield (clipeum virtutis) set up at the senate house (Curia Julia) in the Roman Forum.

25 BC: Augustus marries his daughter Julia to Marcellus (his sister's son)

23 BC, June: Augustus lays aside the Consular office he has held continuously since 31 in order to allow more aristocrats a chance at prestige; he receives in return imperium maius, which gives him authority over all other magistrates and commanders, and tribunicia potestas which gives him broad legislative authority. On the domestic side, his nephew and son-in-law Marcellus dies, so Augustus makes Agrippa divorce his wife and marry Julia, who then bears three sons, Gaius, Lucius and Postumus, and two daughters, Agrippina and Julia.

22 BC: Journey to the East: Athens, Eleusis (where he is initiated), Peloponnese, Samos, Syria, etc.

20 BC: Through diplomatic negotiations, Augustus recovers standards captured by the Parthians in three wars against Rome; commemorates this event in art and coinage.

13 BC: Agrippa, having received Tribunician Powers in 18 and Imperium Maius in 13 (making him virtually co-emperor) goes on campaign in Pannonia and becomes ill.

12 BC: Agrippa dies; Augustus forces his stepson Tiberius to divorce his wife Vipsania (daughter of Agrippa and Marcella (a niece of Augustus)) to marry Augustus' daughter Julia (Agrippa's widow). Lepidus dies; Augustus becomes Pontifex Maximus in his place (March 6), and is now in charge of Roman religion.
