August is the eighth month of the year in the Julian and Gregorian calendars, and the fifth of seven months to have a length of 31 days. It was originally named Sextilis in Latin because it was the sixth month in the original ten-month Roman calendar under Romulus in 753 BC, with March being the first month of the year. About 700 BC, it became the eighth month when January and February were added to the year before March by King Numa Pompilius, who also gave it 29 days. Julius Caesar added two days when he created the Julian calendar in 46 BC (708 AUC), giving it its modern length of 31 days. In 8 BC, it was renamed in honor of Augustus. According to a Senatus consultum quoted by Macrobius, he chose this month because it was the time of several of his great triumphs, including the conquest of Egypt.
No other month starts on the same day of the week as August in common years, but in leap years, August starts on the same day of the week as February. It ends on the same day of the week as November every year. In years preceding common years, it starts and ends on the same day of the week as May of the following year. In years preceding leap years, it begins and ends on the same day of the week as October of the following year and ends on the same day of the week as February of the following year. In common years preceded by any year, August begins on the same day of the week as March and November and ends on the same day of the week as March and June. In leap years, it begins on the same day of the week as June of the previous year and ends on the same day of the week as September of the previous year. In common years preceded by common years, August begins on the same day of the week as February of the previous year.
In the Southern Hemisphere, August is the seasonal equivalent of February in the Northern Hemisphere. In many European countries, August is the holiday month for most workers. Numerous religious holidays occurred during August in ancient Rome.

The Perseids, a major meteor shower, typically takes place between July 17 and August 24, with the days of the peak varying yearly. The star cluster of Messier 30 is best observed around August.
