You might be wondering why October is not the 8th month of the year. After all, it comes after September, which is the 7th month. So, it would make sense for October to be the 8th month, right?

The history and terminology about the months of the year may correct that misconception.

A Brief History of the Months

The months of the year are based on the Earth's orbit around the Sun. That orbit takes 365.242 days, which we round up to 365 days. This means that every four years, we have a leap year, where we add an extra day to the month of February.

The names of the months come from various sources. Some, like January and March, are named after Roman gods. Others, like June and July, are named after Julius Caesar and Julius Caesar's adopted son, Augustus Caesar.

October is the eighth month of the year according to the Roman calendar, which had only ten months. The months of January and February were added later.

How Did October Become the 10th Month?

The Roman calendar originally had ten months, starting with March and ending with December. The months of January and February were added later.

The Roman calendar was a lunar calendar, which means that it was based on the phases of the moon. The lunar year is about 354 days long, so the Roman calendar had to be adjusted every few years to keep it in sync with the solar year.

In 46 BC, Julius Caesar introduced the Julian calendar, which was a solar calendar. The Julian calendar had 365 days, and it was the first calendar to use a leap year.

The Julian calendar was eventually replaced by the Gregorian calendar, which is the calendar that we use today. The Gregorian calendar is also a solar calendar, but it is more accurate than the Julian calendar. It’s also based on the Earth's orbit around the Sun.

Why Do We Still Call October the 10th Month?

Even though October is now the tenth month of the year, we still refer to it as the eighth month. This is because the names of the months have not been changed to reflect the change in the calendar.

Conclusion

So, there you have it. October is not the 8th month of the year because the months of the year are based on the Earth's orbit around the Sun, not on the Roman calendar.
