## The Meridian Method

The Meridian Method is for questions where several chart systems can contribute. It calculates the relevant charts, keeps points of agreement and tension distinct, then explains the result through Meridian's maintained knowledge base. It is not a vote or a claim that every system says the same thing.

## Compare methods

Meridian publishes a comparison for every pair of the eight methods. These pages explain the inputs, focus and limits of each method side by side. Start with the [eight-method comparison](/compare/), or open a specific pairing:
