Billie Eilish first drew public attention in 2015 with her debut single "Ocean Eyes," and her first EP, Don't Smile at Me, followed in 2017. Her debut album, When We All Fall Asleep, Where Do We Go? (2019), debuted atop the Billboard 200, and its single "Bad Guy" gave her a first Hot 100 number one. The James Bond theme "No Time to Die" won the Academy Award for Best Original Song in 2022. At the Grammy Awards on January 26, 2020, she became the youngest person to win Album, Record and Song of the Year and Best New Artist in the same year.
A tweet first, then the certificate
Astro-Databank grades the data AA. The collector, Craft, quotes birth certificate #1200119135214 "in hand": 12:17 p.m. standard time on December 18, 2001, in Los Angeles.
Earlier, Craft had quoted her Twitter account for the birth data: "11:30 am dec 18th 2001". That is 47 minutes before the certificate. Between the two times the angles change and the planets keep their signs.

Rising sign, midheaven and Moon calculated by us for each time on December 18, 2001, Los Angeles, Pacific Standard Time.
Aries rising, with Capricorn at the midheaven
The ascendant is at 5°24′ Aries and the midheaven at 3°13′ Capricorn. Aries began to rise over Los Angeles at 12:04 p.m. and held the horizon until 1:22 p.m., which leaves 65 minutes before Taurus. Capricorn took the midheaven at 12:04 p.m., the very minute Aries arrived, and kept it until 2:11 p.m.
The tweet's 11:30 a.m. comes 34 minutes earlier, when 17°18′ Pisces was on the ascendant and Sagittarius held the midheaven. So the two sources give a Pisces chart and an Aries one, with every planet in the same sign. Astrologers take Aries rising as a direct, forward first impression and Pisces rising as a softer one.

Mercury just past the midheaven
Mercury is at 4°46′ of Capricorn, 1°33′ further along the sign than the midheaven, and it falls in the 10th house under both Placidus and Whole Sign. That house covers career and public standing, and a planet near the midheaven is said to color how someone is seen in their work. For Mercury, that means words and ideas.
Mercury sextiles Mars in Pisces, 2°29′ from exact. Mars is in the 12th house, the hidden one in the tradition, while Mercury sits in the public 10th.

Moon, Uranus and Neptune in Aquarius, in the 11th house
The Moon at 13°02′, Neptune at 7°01′ and Uranus at 21°54′ are in Aquarius and all fall in the 11th house, the house of groups and long-term hopes. The Moon and Neptune are 6°01′ apart, a wide conjunction that astrologers connect with dreamy, impressionable feeling.
The Moon entered Aquarius at 10:43 a.m. on December 17 and stayed there through December 18, so neither birth time moves it. Saturn in Gemini trines it, 2°47′ from exact, and both signs are air.

Sagittarius Sun with Venus and Pluto in the 9th house
The Sun is at 26°59′ of Sagittarius, Venus at 20°36′ and Pluto at 15°33′. The Sun and Venus are 6°23′ apart and Venus and Pluto 5°03′, a loose chain. All three sit in the 9th house, which tradition links with far travel and higher learning.
The Sun leaves for Capricorn at 11:22 a.m. on December 21, about three days after her birth. Venus sextiles Uranus in Aquarius, 1°17′ from exact. It is her closest aspect, and it links the Sagittarius planets to the Aquarius ones.

Mars in Pisces, Jupiter in Cancer, Saturn in Gemini
Mars is at 7°15′ of Pisces, Jupiter at 12°25′ of Cancer and Saturn at 10°15′ of Gemini, with Jupiter and Saturn retrograde. Mars and Jupiter trine, 5°10′ from exact, both in water. Saturn alone changes house with the system, from the 2nd in Placidus to the 3rd in Whole Sign.
