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
Pisces, February 19 to March 20.
The Fishes, two of them, swimming opposite ways — the books make the sign of the last sign, carrying a little of all the others. Ruled by Jupiter of old and Neptune since, a water sign, credited with imagination, empathy and a porous border between itself and everyone else. Its people are said to feel the room before they enter it. The tradition gives Pisces the artists and the dreamers, and asks them please to remember where they parked.
Astrology, reported rather than endorsed — the astronomy is the part of the book that is real.
