September 21 zodiac sign: Virgo
The September 21 zodiac sign is Virgo at midday in every year from 1930 to 2029 — but not at every hour: in 1 of those 100 years a birth at the end of the day, in time zones well behind Greenwich, had the Sun already in Libra.

Mercury wires the sign for analysis and talk — quicker, more articulate, less settled. The last ten degrees of Virgo already turn toward Libra, which is why this third often reads as the most complicated.
Personality

The Moon and nakshatra columns change every year because the Moon returns to the same calendar date in a different position — which is why a birth date alone cannot tell you those, and why this table exists.

The most frequent is 7 with 12 years; every other number turns up in 11 years. No master number is possible on this date: every year from 1930 to 2029 reduces to a single digit.
Why the answer almost always holds
September 21 sits 29 days past the start of Virgo and reached 28°31′ this year — close enough to the end of the sign that the hour starts to count: in 1 of those 100 years a birth at the end of the day, in time zones well behind Greenwich, had the Sun already in Libra. At midday it is Virgo in every year tested, so on this date the question worth asking is the birth time, not the birth year.
