There is some dispute over the year of Caesar's birth. Some scholars have made a case for 101 or 102BC as the year of his birth, based on the dates that he held certain magistracies, but scholarly consensus favors 100BC. Similarly, some scholars prefer 12 July for the day of his birth, but others give 13 July. Goldsworthy, p. 30, Ward, Heichelheim, & Yeo p. 194. For a source arguing for 12 July, see Badian in Griffin (ed.) p.16
