September comes from the Latin septem, meaning seven, because it was the seventh month of the Roman calendar.  That's why I think the month should be renamed.  I don't know what to call it but it doesn't seem to make a lot of sense to me.

How did we get into the rut of the final four months ending with the letters b-e-r? October also coincides with the number eight because it's the eighth month of the Roman calendar. You guessed it November is synonymous to nine.  December was the tenth month of the Roman calendar.

We currently use (along with most of the world) the Gregorian calendar which is named after Pope Gregory XIII, who introduced it in October 1582.

The original goal of the Gregorian calendar was to change the date of Easter.  The Julian calendar was introduced by Julius Caesar in 46 B.C.  The famous Roman's system miscalculated the solar year, so it fell out of sync with the seasons.  It concerned Pope Gregory because it meant Easter would fall further away from the spring equinox each year.

Let's see, we could rename September, Petiole (the slender stalk by which a leaf is attached to it's stem according to dictionary.com).  After all the leaves begin to fall in September and Autumn or Fall starts then.

With that logic I suppose we would have to rename October, November and December also.

Got any ideas?
