If your birthday is in September before 23 September, your star sign is Virgo. From 23 September onwards it is Libra. The changeover can move by a day in some years, so for a birthday right on 23 September it's worth checking the year.
September zodiac sign dates
- Virgo: 23 August to 22 September
- Libra: 23 September to 22 October
Where the Sun really is in September
The Sun is in Leo until about 16 September and in Virgo after that. The start of Libra is set by the autumn equinox, when day and night are about equal, on 22 or 23 September.
The September gap between sign and constellation comes from the slow wobble of the Earth's axis. The zodiac signs and constellations guide explains why Virgo and Libra have drifted, and Ophiuchus is the one the signs leave out.
What is in the September evening sky
September evenings have the Square of Pegasus rising in the east and Aquarius low in the south-east. The Summer Triangle is moving west, and on a dark night away from towns the Milky Way runs overhead from Cygnus down towards the southern horizon.
Virgo and Libra in the sky
The brightest point of Virgo is Spica, and of Libra, Zubeneschamali. Both are drawn in the series of twelve Virgo constellation print and Libra constellation print, in near-black, gold and warm ivory.
Virgo and Libra belong to different elements: the zodiac elements guide sorts all twelve signs into fire, earth, air and water.
