About September 2026

Four months in a row — September, October, November, December — still carry Latin numeral names (seven, eight, nine, ten) that stopped matching their actual calendar position once Numa Pompilius's reform gave the year two new opening months. September's autumn equinox, around the 22nd or 23rd in the Northern Hemisphere, marks the same date as the Southern Hemisphere's spring equinox. Sapphire is the traditional birthstone, the aster and morning glory the birth flowers, and the zodiac runs from Virgo to Libra around the 22nd or 23rd. It's a small but genuine reminder that calendars are historical artifacts, not purely logical systems.

Hispanic Heritage Month in the US runs from September 15 through October 15, deliberately spanning two calendar months to align with the independence days of several Latin American countries that fall in that window.

College and professional US football seasons both begin in September, kicking off a period of sharply increased sports-related media and retail spending that runs into winter.
