20 Interesting Facts About October
1. The “Eighth” Month is the Tenth
October’s name is a colossal lie! It derives from the Latin word “octo,” meaning eight, because it was the eighth month in the original, ten-month Roman calendar. The months of January and February were added after the initial naming, pushing October back to the tenth spot, but the name stuck.
2. It’s the only month that ends on the same day of the week as February
October always ends on the same day of the week as the preceding February, as long as it’s a non-leap year (e.g., in a non-leap year, if October 31st is a Tuesday, then February 28th was also a Tuesday).
3. A Day Vanished from October
In 1582, when Pope Gregory XIII introduced the Gregorian calendar to correct the accumulated error of the old Julian calendar, the day following Thursday, October 4, 1582, suddenly became Friday, October 15, 1582. Ten days simply ceased to exist for those who adopted the new system, creating a historical gap in official records.
4. October’s Old English Name was “Wine Month”
Before the Norman Conquest, the Anglo-Saxons had names for their months. October was sometimes called “Wyn Monath” (Wine Month) in reference to the season’s grape harvesting and pressing, and sometimes “Winterfylleth” (Winter-Full-Moon) as its full moon marked the traditional beginning of winter.
5. October Is Known as the Month of Transformation
From falling leaves to harvest moons, October symbolizes change and letting go. Many cultures see it as a month for reflection and preparation for the darker months ahead.
6. The Day the Internet was Born… and Crashed
The first message ever sent over the ARPANET, the precursor to the internet, took place on October 29, 1969. The message was supposed to be the word “LOGIN,” but the system crashed after only the first two letters, “LO,” were transmitted, leaving the internet’s debut as an unexpectedly brief communication.
7. Two Zodiac Signs Rule October
Born in early October? You’re a Libra—balanced and charming. Born after the 23rd? You’re a Scorpio—mysterious and intense. These two signs add plenty of personality to the month
8. October Kicks Off World Space Week
The United Nations declared October 4–10 as World Space Week to celebrate the launch of the first human-made satellite, Sputnik 1, on October 4, 1957, and the signing of the Outer Space Treaty on October 10, 1967. It’s an annual celebration of science and technology’s contribution to humanity.
9. October is the Fourth Most Common Birth Month

15. The Hunter’s Moon is an October Special
The full moon that appears in October (or sometimes early November) is traditionally called the Hunter’s Moon. It gets its name because its bright, early-rising light traditionally provided hunters with extra time to gather food before winter set in.
