July has two zodiac signs: Cancer until 22 July, and Leo from 23 July.

| Born | Sign | Constellation · brightest star |
|---|---|---|
| 1–22 July | Cancer | Cancer · Tarf |
| 23–31 July | Leo | Leo · Regulus |
These are the usual calendar dates. The moment the Sun moves from Cancer into Leo shifts slightly between years, so a birthday on the boundary can fall either side. A birth chart calculated for the exact minute and place shows where the Sun stood.
