The name October may seem like it doesn’t match the number 8, but it actually has historical and linguistic roots that explain why it is the eighth month in the modern Gregorian calendar, even though its name suggests something else. To understand why october means "eight," we have to look back to the origins of the calendar and the evolution of months.

Origins in the Roman Calendar

The name "October" comes from the Latin word octo, which means eight. This is because October was originally the eighth month in the Roman calendar, which was the precursor to the Gregorian calendar that most of the world uses today.

The Roman calendar, before it was reformed, began in March (not January) and consisted of just 10 months. The first month, Martius (March), was followed by April, Maius (May), Junius (June), Quintilis (July), Sextilis (August), September (meaning "seven"), October (meaning "eight"), November (meaning "nine"), and December (meaning "ten"). In this early calendar system, october was the eighth month, which is why its name still reflects that number.

Calendar Reforms: Julian and Gregorian Calendars

The Roman calendar was later reformed in 46 BCE by Julius Caesar, who introduced the Julian calendar. The Julian calendar added two months—January and February—at the start of the year to better align the calendar with the solar year. As a result, the months of the year shifted, and October became the tenth month instead of the eighth.

However, even though October moved to the tenth position in the Julian calendar and later in the Gregorian calendar (introduced in 1582 by Pope Gregory XIII), its original name was retained. This meant that the name "October" continued to reflect its historical position as the eighth month, even though it was now the tenth month in the modern calendar.

Why the Number Shift?

The addition of January and February to the beginning of the year was designed to bring the calendar year more in sync with the solar year, which is roughly 365.24 days long. This helped eliminate the drift that had occurred in earlier Roman years and made the calendar year more accurate. However, rather than renaming the months to reflect their new positions in the calendar, the Roman names for the months were preserved.

The Legacy of October's Name

Today, we use the Gregorian calendar, and October is the tenth month, but its name still harks back to its ancient position as the eighth month in the Roman calendar. Despite the shift in its position, the name "October" is a reminder of the evolution of our timekeeping systems and how language can preserve the past.

Conclusion

In summary, October means "eight" because of its origins in the ancient Roman calendar, where it was originally the eighth month. Although the calendar has since been adjusted to start in january, and October is now the tenth month, the name has remained unchanged. Thus, October's name is a reflection of history and how language and tradition preserve the past, even when the structure of the calendar itself has evolved.
