About October 2025

October's name comes from the Latin 'octo' ('eight'), its position as the eighth month in the earliest Roman calendar, a numbering that stuck even after the calendar was later restructured to begin in January. Northern Hemisphere October brings mid-autumn cooling and shortening days; the Southern Hemisphere experiences mid-spring warming over the same weeks. The zodiac spans Libra (until around the 22nd) and Scorpio (from the 23rd), with opal and tourmaline as traditional birthstones and the marigold and cosmos as birth flowers.

The US observes October as both National Book Month and Breast Cancer Awareness Month, the latter formally recognized by Congress since 1985 and now marked by pink-ribbon campaigns from countless organizations.

Many US companies hold their fiscal fourth-quarter planning and budget cycles in October, making it a notably busy month for corporate finance teams ahead of year-end.
