Why August is the 8th month of the year?

Wow, time actually runs fast. Today is the 2nd day of August. Why August is the 8th month of the year? I was just wondering how people came up with Month names. Let's start with August. It is the 8th month of the Gregorian calendar. In Astrology, August begins with the sun in the sign of Leo and ends in the sign of Virgo. This month was originally named "Sextilis" in Latin because it was in the first place, the sixth month in the ancient Roman calendar in which started with March. Then it later became the eighth month when January and February were added to the beginning of the year. August was renamed in honor of Augustus. Actually, August originally had 29 days in the Roman calendar. Augustus took two days from February and added it to August when Sextilis was renamed in his honor. Sounds interesting huh?
