What the sign label means
The final sidereal segment before the circle returns to Aries. Longitudes wrap from 359.99° back to 0°.
A body is listed in Pisces when its normalized sidereal longitude falls from 330°00′ up to—but not including—360°00′. The exact degree within the sign remains important, particularly near either edge.
Sign is not the same as house
The sign is a fixed part of the 360° circle. In a whole-sign chart, the house number depends on the ascendant: the rising sign is house one, and the following signs are numbered in order. Pisces can therefore be a different house in different birth charts.
Element and mode are traditional classification labels. They do not, on their own, establish a personality or predict an event.
