Sabrina Carpenter doesn't know the exact birth time, and has said so with a smile. Born on 11 May 1999 in Quakertown, Pennsylvania, Sabrina has a Taurus Sun for certain, and a Pisces or Aries Moon: the Moon stayed in Pisces until about 4:52 pm that day, so a morning birth means a Pisces Moon.
The best answer to this question comes from Sabrina Carpenter, in a WIRED Autocomplete video from December 2021. Reading the search "What time was Sabrina Carpenter born?", Sabrina said: "You and me both wanna know. My mom tells me this every couple of years and I always forget. I think it's 8:52 in the morning, but then some years it's 11:52 cause I don't remember. But it was in the morning, I believe."
That's honest and very relatable, and it leaves two candidates three hours apart. Astro-Databank and Astrotheme both rate the time DD, meaning unconfirmed, for exactly this reason. In Nylon in February 2022, Sabrina added: "I'm a Taurus… I also believe I'm a rising Pisces, if I'm not mistaken." Astro-Databank suggests the Pisces may really belong to the Moon, and the sky supports that: through every morning hour of 11 May 1999 the Moon was in Pisces.
With three planets in Taurus, this chart is built on steadiness, taste and staying power. The Sun, Mercury and Saturn share the sign, so feeling, thinking and discipline all move at the same unhurried, sure-footed pace. Taurus is ruled by Venus and loves melody, texture and pleasure, and Mercury here gives words a sensual, memorable shape. Mercury's tight square to Neptune adds a lyricist's ear for double meanings and dreamy imagery.
Venus in Cancer brings a protective, nostalgic warmth. Mars in Libra, retrograde, wins people over with charm and fairness rather than force, and Jupiter in Aries backs bold moves with good luck. A Pisces Moon, the likely one, is empathetic and creative, at home in music and make-believe, and it softens all that Taurus steadiness with a dreamy, playful streak.
Knowing the minute would settle the rising sign and the houses. The two remembered times give different answers: 8:52 am would put the rising sign in Cancer and 11:52 am would put it in Leo. Neither would make it Pisces; that sign was rising only between about 2:36 and 3:48 am that day. Both morning times keep the Moon in Pisces, which is why the Moon is the likelier home for the Pisces that Sabrina remembers.
