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
Aries, March 21 to April 19.
The first sign, and the tradition treats it that way: the Ram is the one who goes first — through the door, into the argument, off the cliff. Ruled by Mars, a fire sign, and the books credit it with courage, impatience and a short memory for grudges, which is a generous way of saying it has already moved on. Its people are supposed to start things. Finishing them is what the other eleven are for.
Astrology, reported rather than endorsed — the astronomy is the part of the book that is real.
