What does Moon Square Mercury mean?

Square (90°): friction, pressure, growth. Here consensus doesn’t arise, movement does; two forces disrupt each other just enough that you have to change something in the world to keep living. Squares are uncomfortable and produce the most stories — whoever walks through a square comes out different. Here Moon (your feelings and instincts) meets Mercury (how you think and speak). 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.
