What does Mercury Opposition Mars mean?

Opposition (180°): two poles ask for a decision or a balance. Neither side wins for long — you oscillate, and the oscillation is the point. Oppositions often show up through other people: whoever stands across from you carries the side you haven’t yet lived, and brings it back to you until you recognise both halves. Here Mercury (how you think and speak) meets Mars (your drive and your anger). How it feels depends on how tight the aspect is: the smaller the orb, the more strongly it shapes you.

Do I need my birth time?

For the planets involved the birth date is often enough. For an exact result — especially with the fast-moving Moon — your precise time helps.

What if I do not have this aspect?

That is completely normal — nobody has every aspect. The calculator still shows how close you are, and you can check more aspects below.

How accurate is the calculation?

Accurate to the arc-second. We use the Swiss Ephemeris library on the NASA dataset — the same standard professional astrology software runs on.
