Frequently asked questions
What does the Mars sign show?
In astrology, Mars is the planet of action: it speaks of energy, initiative, courage, anger and desire. It shows how a person goes after what they want.
Do Mars and Venus form a pair?
Yes. Venus shows what a person values and how they love; Mars shows how they pursue and desire. That is why the two are widely used to compare couples.
Do I need my time of birth?
Almost never. Mars takes about two months to cross a sign, so the time only matters if you were born on the day it changed signs.
