October 31 — the date, kept whole
The sign
The Sun on October 31 sits firmly in Scorpio — in every one of the 101 years we computed. No cusp asterisk on this one.
A deep, intense water sign, Scorpio carries the probing, powerful energy of late autumn. As a fixed sign it is traditionally read as focused and unwavering, drawn to what lies beneath the surface. In astrology it is tied to transformation, mystery, and passion, and modern astrology adds Pluto to its traditional ruler, Mars. It is often seen as the most private and determined of the signs, feeling everything deeply. More on Scorpio →
The flower and the stone
October's birth flower is the Marigold (with the Cosmos beside it), and its stone is the Opal — Iridescent. Each carries meanings from its own tradition; the month pages keep their stories.
The month's moon
October's full moon is the Hunter's Moon — themes of preparation, turning inward, the last light. The date tool shows the exact moon of any October 31, any year.
One line of numerology
Day 31 reduces to 4 in the day-number tradition. Four is read in tradition as the builder's number — steadiness, method, and trust in slow, honest work.
The sky of your actual birthday
Everything above belongs to the date. The sky belongs to the year, the minute, and the place — where the Moon sat, what was rising, the whole wheel. The calculator draws it free, on your device.
