Birthday facts
Born on July 31.
Everyone born on July 31 is a Leo — ruled by the Sun, generous, and would like that noted. The stone is ruby, the flower larkspur, and the day is shared with J. K. Rowling and Geraldine Chaplin.
Your book
Born on July 31? 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
Leo, July 23 to August 22.
The Lion, ruled by the Sun itself, and the books do not pretend otherwise: this is the sign of the centre of the room. A fire sign, credited with warmth, generosity and a need to be seen that its people would call a gift for being seen. The tradition gives Leo courage and a big heart and a weakness for applause, and notes that it tends to earn the applause, which is the annoying part.
Astrology, reported rather than endorsed — the astronomy is the part of the book that is real.
