March has two zodiac signs: Pisces until 20 March, and Aries from 21 March.

| Born | Sign | Constellation · brightest star |
|---|---|---|
| 1–20 March | Pisces | Pisces · Alpherg |
| 21–31 March | Aries | Aries · Hamal |
These are the usual calendar dates. The moment the Sun moves from Pisces into Aries 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.
