January month number

August was named after the Roman Emperor Augustus, who was the first emperor of the Roman Empire and ruled from 27 BC until his death in AD 14. The month was originally named Sextilis in Latin, which means "six", as it was the sixth month in the early Roman calendar, that had only 10 months.

However in 45 BC Julius Caesar instituted reforms that created the Julian calendar. Under the Julian calendar, January and February were added, and the year was made to start in January instead of March. This change caused August to become the eighth month in the Julian calendar

In 8 BC, the Roman Senate decided to rename the month to Augustus in honor of the first Roman Emperor, Augustus, as it was the month of his greatest triumphs, including the conquest of Egypt.
