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
Taurus, April 20 to May 20.
The Bull is ruled by Venus, and the books make it the sign of pleasure taken slowly — good food, good cloth, a chair that is exactly right. An earth sign, credited with patience, loyalty and a stubbornness so complete it stops looking like a fault and starts looking like a policy. Its people are said to be the ones you can lean on, provided you do not try to hurry them.
Astrology, reported rather than endorsed — the astronomy is the part of the book that is real.
