October month number

October is the tenth month of the year, its name comes from the Latin word "octo," which means eight. October was originally the eighth month in the Roman calendar, which only had ten months and began in March. During the reign of King Numa Pompilius (circa 713 BC), the Roman calendar underwent some revisions which included the addition of two new months, namely January and February. In 153 BCE, it was officially declared that January 1 would be recognized as the first day of the year, causing October to be designated as the tenth month.

The month of October is associated with the arrival of autumn in the Northern Hemisphere and with harvest season. In the United States, October is known for Halloween, an annual holiday celebrated on the night of October 31st.
