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
Libra, September 23 to October 22.
The Scales, ruled by Venus, and the only sign that is an object rather than a creature — the books make much of that. An air sign, credited with a sense of fairness, an eye for beauty and a talent for company; blamed for taking a very long time to choose, because both sides really do have a point. Its people are supposed to keep the peace, and to look good doing it.
Astrology, reported rather than endorsed — the astronomy is the part of the book that is real.
