Dates use the tropical zodiac. "Part of sign" splits each sign into three parts of about ten days (decans), ruled by the sign itself and then the next two signs of the same element.
September 1 to 22: Virgo
Virgo is a earth sign ruled by Mercury. People born on these dates tend to be analytical, hard-working and kind, and can struggle with being overcritical and worrying. Read the full Virgo profile or see this month's Virgo horoscope.
September 23 to 30: Libra
Libra is a air sign ruled by Venus. People born on these dates tend to be diplomatic, fair-minded and social, and can struggle with being indecisive and people-pleasing. Read the full Libra profile or see this month's Libra horoscope.
September cusp dates
The shaded rows above (September 21, September 22, September 23 and September 24) sit next to a change of sign. The Sun moves into the next sign at a slightly different hour each year, so on these days the sign you see in a table may not match your own chart. Your birth time and place settle it.
