Arthur Fleck: zodiac sign and birth chart

Arthur Fleck has no canon birthday. The film never gives one. Read from his personality, he's a Cancer: a clown who takes care of his mother, writes his jokes in a notebook and feels every cruelty twice as hard. A Pisces Moon is the dream he keeps living in.

NEBO's take

No birthday in canon. His personality says Cancer.

We ran Arthur through the same model that matches people to characters in the app, and looked at which chart gets him most often. It reads him as water almost everywhere: sensitive, protective of home and hurt hard by rejection.

NEBO's take

Cancer SunRead from his personality

Sun CanonNot in canonNEBO's takeCancer
Cancer takes care of home. Arthur bathes his mother and gets her through the evening, even when he has nothing left.
Moon CanonNot in canonNEBO's takePisces
Pisces Moon lives in a dream version of life. He pictures himself on Murray Franklin's show, the audience laughing with him instead of at him.
Rising CanonNo birth timeNEBO's takeCancer
No birth time in canon. First impression: a clown on a corner with a sign, soft-spoken and easy to push around.
Mercury CanonNot in canonNEBO's takeCancer
Cancer Mercury writes it down. His joke notebook is where he keeps what he can't say out loud.
Venus CanonNot in canonNEBO's takeCancer
Cancer Venus craves warmth. Every night he watches Murray Franklin with his mother, and treats the host as the father he never had.
Mars CanonNot in canonNEBO's takeCancer
Cancer Mars lashes out when cornered. The subway is where the quiet man stops being quiet.

What canon does give: a lonely man in a city that stopped looking out for him. Cancer answers with a need to care for someone, anyone.
