What does September mean in the latin language?

Answer 1

September comes from the Latin root "septe", meaning "Seven".

Curiously, several of our months come from Latin numbers, and they're all off by two. "September" for seven, even though that's the 9th month, "October" from "octo" for eight when October is the tenth month, "November" from "nona" for nine, and December from the Roman word for ten, when December is the 12th month.

The reason for the disconnect is that the Roman months were numbered that way because the year began around the time of the spring equinox, which is in March.

Answer 2

In Latin, "septi" means seven and "septem" means seventh. September really was the seventh month in the ancient Roman calander, so that was its name.

Answer 3

September is named for the Roman calendar in which it was the 7th month. Septem means seven. October is the eighth month, November: the ninth and December, the 10th month.
