March 15 in profile
Late degrees of Pisces carry the sign’s lessons in concentrated form: compassion, surrender, imagination and the need to let things go. The Scorpio decan, with Mars as sub-ruler and Pluto in modern readings, adds staying power and a taste for transformation. A March 15 Pisces often lives in cycles, giving everything to a phase of life and then closing it completely. Friends notice they come back from hard seasons changed, with sharper judgement and the same kindness.
Recharging means going under for a while. A free evening is rarely enough; they need whole days of retreat with the phone off, curtains half drawn and a long novel or a series watched start to finish. Sleep is their main repair tool, and they guard it closely. After a big social event they may need two quiet days. People who take this personally misunderstand it, since the retreat is what makes their warmth possible.
Courage arrives late and then all at once. They will think for a year about leaving a job or a city, say nothing, and then hand in notice on a Tuesday. The Mars sub-ruler gives them nerve once the decision is made, and they rarely look back. The useful habit is telling one person when the thinking starts, so the leap is not taken entirely alone.

Compatible signs for a Pisces
Sun-sign compatibility starts from the element. Pisces gets on most easily with its own element and with the two sextile signs, and feels the strongest pull from its opposite. For a March 15 birthday, in the Scorpio decan, Scorpio is a natural match. The full charts decide how a real pairing feels.
