The name for October is derived from the Latin “Octo” meaning “eight” which came after September (derived from Latin for seven) the seventh month of the Roman calendar until 46 BC. In 46 BC the beginning of the year was changed to from March to January.
The traditional full moon name for October is the “Cold Moon”. In most years the Moon is also called the “Hunter’s Moon” because it is the first full moon after the fall equinox, but it could also be a “Harvest Moon”. The “Harvest Moon” is somewhat unique in that the name is assigned to the full moon closest to the autumn equinox. This means the “Harvest Moon” can happen in October or September.
Other names include the "Blood Moon", or "Sanguine Moon". To the Natchez it’s the “Turkey Moon”. The Oglala Sioux called it the “Moon of the Changing Season”. The Cheyenne named it “The Moon when Water Freezes at the Edge of the Stream”. The Taos call it “The Corn Ripe Moon” and the Oto call it “Deer Rutting Season Moon”. Moon:

October 31: Cross-quarter day (Halloween). Cross-quarter days occur half way between the seasons. They mark the time when we start to feel the effects of the upcoming season. Although winter does not officially start until December 21 (winter solstice), by Halloween we begin to feel the effects of old man winter.
October 23: Partial Solar Eclipse. The Moon will cover 45% of the sun here in Denver. (DO NOT LOOK DIRECTLY AT THE SUN WITHOUT PROPER EYE PROTECTION). Go here or here for information on how to view a solar eclipse safely. From NASA: Unsafe filters include all color film, black-and-white film that contains no silver, photographic negatives with images on them (x-rays and snapshots), smoked glass, sunglasses (single or multiple pairs), photographic neutral density filters and polarizing filters. Most of these transmit high levels of invisible infrared radiation which can cause a thermal retinal burn. The fact that the Sun appears dim, or that you feel no discomfort when looking at the Sun through the filter, is no guarantee that your eyes are safe. Solar filters designed to thread into eyepieces that are often provided with inexpensive telescopes are also unsafe. These glass filters can crack unexpectedly from overheating when the telescope is pointed at the Sun, and retinal damage can occur faster than the observer can move the eye from the eyepiece.
Solar eclipse begins: 3:18pm MDT
Greatest eclipse: 4:35pm MDT
Solar eclipse ends 5:44pm MDT
October 24, 1601 – Tycho Brahe, the astronomer who made the first accurate measurements of star positions, dies.
