Your book
Born on December 9? Add the year.
Then it is a pop-up book: the sky the day you arrived, the No. 1 that week, the president, what a stamp cost, your life in weeks, and who was exactly your age when they did the thing they are known for — and at the end, a birthday poster of the day, engraved, to take home. One field. The date lives after the # in the link, which no server sees — nothing about you leaves your browser.

The old books say
Sagittarius, November 22 to December 21.
The Archer, half horse and aiming somewhere over the horizon; ruled by Jupiter, the planet of more. A fire sign, and the books credit it with optimism, honesty to a fault and a need to be elsewhere — the traveller, the student, the one with the ticket already booked. Its people are supposed to say the true thing before checking whether anyone wanted it said. The tradition forgives them, mostly.
Astrology, reported rather than endorsed — the astronomy is the part of the book that is real.
