Thanks for ruining my day. Now I'm going to be thinking about "months" all day long. It has never occured to me that September, etc. were named with prefixes. The only explanation I can see is that these months were indeed seven through ten on some calendar at some time. However, if ANYONE has an explanation that they are certain of, please post it for Eileen's students and for my sanity.
On 10/23 Eileen was talking about prefixes:
>One of the students said - The months of the year - September, >October, November, December, and began saying that is the same as the >months. September is the 7th month. Suddenly several of the students >said - no its not its the ninth month. The next question was - Why >are the prefixes used differently with the months? Or, has there >ever been a time when September was the 7th month of the year? Or, >when were the months named, and were they intentionally named using >these pre-fixes?
