Meaning & origin
September entered the U.S. baby name charts in 1955, making it a relatively modern addition. Its highest popularity came in 1977, when it ranked its peak year. Since 1985 the name has been in decline, reflecting a broader trend away from month names after a brief surge in the 1970s. In 2025, September ranked 5,917th, with just 1 in 80,363 girls receiving the name. The name has never been recorded among the top states, indicating its sporadic, scattered usage across the country. As a word name tied to the autumn equinox, September appeals to parents drawn to seasonal, evocative choices that carry a sense of change and new beginnings.
September is derived from the Latin "septem," meaning seven, as it was the seventh month in the early Roman calendar before January and February were added. The use of month names as personal names is a modern English practice, particularly in the United States, where they are sometimes chosen for their distinctive sound or seasonal associations.
