September 21 zodiac sign
Late and urgent, the Sun at about 28° Virgo on September 21 concentrates the sign’s lessons in the final Venus decan, with Libra waiting only a degree or two away.

September 21 in profile
In almost every case this date is Virgo, though anyone born far from Greenwich time may want to check an exact chart, since Libra is very close. The Sun at 28° sits in the third decan, Taurus as sub-sign and Venus as sub-ruler, at the point where Virgo has learned most of what it can. A September 21 Virgo carries the sign’s accumulated wisdom with a little restlessness, aware that a new phase lies just ahead.
Anger is rare and well reasoned. They try to fix problems before they become arguments, and they tend to apologise for things that were not entirely their fault. When pushed too far, they lay out the facts calmly and decisively. They dislike scenes and will leave a room rather than shout, returning later with a clear, practical proposal. A sincere apology from the other side ends the matter quickly.
Under pressure they look for order and beauty at once. A tidy room, a walk in a garden, a favourite album played twice can reset them. Stress makes them restless and quietly critical of themselves. They benefit from someone who reminds them that most things are fine. The useful habit is noticing the inner critic and turning the volume down a notch.
Virgo near the cusp
In every year from 1930 to 2040 the Sun was in Virgo for the whole of September 21 in Greenwich time (UTC). The change of sign happens within a day of this date, though, so a birth in a time zone far from UTC (New Zealand, Hawaii or the Pacific) can fall in Libra. If that is you, the birth chart calculator settles it from your time and city.
Calculated by Lunonis from the same ephemeris code as our charts (astronomy-engine, checked against Swiss Ephemeris): geocentric, tropical zodiac, true equinox of date. Times are UTC: add or subtract your time zone’s offset, which can move the change to the day before or after.
Your Moon sign depends on the year
The Sun is in the same place on September 21 every year; the Moon is not. It changes sign every two and a half days, so people who share this birthday can have any of the twelve Moon signs. Here is where it was on September 21 in recent years, from 00:00 to 23:59 UTC (an arrow means it changed sign during the day).

Compatible signs for a Virgo
Sun-sign compatibility starts from the element. Virgo gets on most easily with its own element and with the two sextile signs, and feels the strongest pull from its opposite. For a September 21 birthday, in the Taurus decan, Taurus is a natural match. The full charts decide how a real pairing feels.

Asked about September 21
What zodiac sign is September 21?
September 21 is Virgo. In Greenwich time the Sun is in Virgo all day in every year from 1930 to 2040; only a birth in a time zone far from UTC can fall in Libra.
Is September 21 a cusp birthday?
Only just. September 21 is next to the day the Sun changes sign, so it is Virgo in UTC but can be Libra for births in far eastern or western time zones. There is no blend of the two: a chart with the birth time and city gives one sign.
What decan is September 21?
September 21 falls in the 3rd decan of Virgo. In the triplicity system we use, that decan belongs to Taurus and its ruler Venus, which colours the Virgo Sun with a little of Taurus.
Your birthday is only the Sun
A September 21 birthday tells you where the Sun was. The Moon, the Rising sign and eight more planets each sit somewhere of their own, and they depend on the year, the hour and the place. The free calculator shows all of them.
