Your book
Born on June 21? 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
Cancer, June 21 to July 22.
The Crab, ruled by the Moon, and the books make it the sign of home — the one who remembers your birthday, keeps the photographs, and knows where everything is. A water sign, credited with loyalty, intuition and a memory that forgets nothing, kind or otherwise. The shell is the point: soft inside, and it takes a while to get there. Its people are said to feel everything, which is a talent as much as a burden.
Astrology, reported rather than endorsed — the astronomy is the part of the book that is real.
