Frequently asked questions
What is a Mars sign?
Your Mars sign rules your drive: how you take action, chase what you want, assert yourself, handle anger and express physical and sexual energy. It is the engine of your chart.
Do I need my birth time for my Mars sign?
Usually no. Mars stays in a sign for around six to seven weeks, so your date of birth is enough except on the rare day it changes signs.
What does Mars say about passion?
Where Venus shows how you love, Mars shows how you pursue and how you express desire and drive. Together they describe your whole romantic and sexual style.
