August

Chambers's Encyclopaedia, Volume 1: A to Beaufort, p. 572

August, the sixth month in the Roman year, which began with March, was originally styled Sextilis, and received its present name in honour of the Emperor Augustus, several of the most fortunate events of his life having occurred during this month. In this month he was first admitted to the consulate, and thrice entered the city in triumph. In the same month, the legions from the Janiculum placed themselves under his auspices, Egypt was brought under the authority of the Roman people, and an end put to the civil wars. To make it equal with the fifth month, whose name had been changed from Quintilis to Julius in honour of Julius Cæsar, a day was taken from February and added to August.
