August is the eighth month of the year in the Gregorian Calendar and one of seven Gregorian months with a length of thirty-one days.
This month was originally named ‘sextilis’ in Latin, because it was the sixth month in the original ten-month Roman calendar under Romulus in 753 BC, when March was 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 twenty-nine days. Julius Caesar added two days when he created the Julian calendar in 45 BC giving it its modern length of thirty-one days. In 8 BC it was renamed in honour of Augustus, who did not take a day from February. He chose this month to take his name rather than his birth month – which was traditional – as a mark of honour to the defeated Queen Cleopatra the last ruler of Egypt, this being her birth month.
In the Southern Hemisphere, August is the seasonal equivalent of February in the Northern Hemisphere.
In common years no other month starts on the same day of the week as August, though in leap years February starts on the same day. August ends on the same day of the week as November every year.
