Why is September called September? Most people don’t know!

I still see those teenagers

standing in the playground of the new semester in September

looking up at the sky with clear eyes

towards the infinite future

——Xu Wei's "Juvenile"

tomorrow is September 1st, the school day, autumn will follow Is approaching.

But have you ever wondered, why is September called September?

September is September

Why are Septwolves

and not nine wolves?

October is October

Why Octopus is an octopus (octopus)

instead of a ten-claw?

December is December

Why is decade

instead of twelve years?

This is because, in the Roman calendar, only ten months a year, that has the following correspondence relationship:

November please refer to the following information:

September (from Latin septem, "seven") or mensis September was originally the seventh of ten months on the ancient Roman calendar that began with March (mensis Martius, "Mars' month"). It had 29 days. After the reforms that resulted in a 12-month year, September became the ninth month, but retained its name.

It is said that the English term of the month in the Gregorian calendar is actually related to the ancient Roman calendar, so:

September is actually July

so the root sept- is "seven"

Septwolves is the seven wolves

October is actually August

so the root octo- is "eight" z3 Zz

octopus is an octopus

December is actually October

so the root dec- is "ten"

decade is ten years
