SharpAstrology Packages

Calculate aspects with defined orbits

In Western astrology, the distances between planets are assigned certain aspects. Each planet is assigned a certain range, an orbit. This package provides an OrbitBuilder to define these orbits freely.

You can use default orbits

using SharpAstrology.DataModels;
using SharpAstrology.Enums;
using SharpAstrology.Ephemerides;
using SharpAstrology.ExtensionMethods;
using SharpAstrology.Utility;


var date = new DateTime(1988, 9, 4, 1, 15, 0, DateTimeKind.Utc);
using var eph = new SwissEphemeridesService("[PATH_TO_EPHEMERIDES_FILES]").CreateContext();

// create chart
var chart = new AstrologyChart(date, eph);

// Aspects with default western orbits
var aspect = chart.AspectBetween(Planets.Sun, Planets.SouthNode);
Console.WriteLine(aspect);
// Output: Conjunction

// Use default western orbits explicitly
var orbitBuilder = OrbitBuilder.WithWesternDefaultOrbits();
var orbits = orbitBuilder.Build();
aspect = chart.AspectBetween(Planets.Sun, Planets.SouthNode, orbits);
Console.WriteLine(aspect);
// Output: Conjunction

// Change specific orbit definitions
orbitBuilder.SetRule(Aspects.Conjunction, Planets.Sun, 1);
orbitBuilder.SetRule(Aspects.Conjunction, Planets.SouthNode, 1);
orbits = orbitBuilder.Build()
aspect = chart.AspectBetween(Planets.Sun, Planets.SouthNode, orbits);
Console.WriteLine(aspect);
// Output: None

You can load orbits from json

using SharpAstrology.DataModels;
using SharpAstrology.Enums;
using SharpAstrology.Ephemerides;
using SharpAstrology.ExtensionMethods;
using SharpAstrology.Utility;


var date = new DateTime(1988, 9, 4, 1, 15, 0, DateTimeKind.Utc);
using var eph = new SwissEphemeridesService("[PATH_TO_EPHEMERIDES_FILES]")
    .CreateContext();

// create chart
var chart = new AstrologyChart(date, eph);

// Define orbits with json string
var orbitBuilder = OrbitBuilder.FromJsonString("""
{
    "conjunction": {
        "sun": 10,
        "southnode": 8,
        "moon": 10
    }
}
""");
var orbits = orbitBuilder.Build();

Console.WriteLine(chart.AspectBetween(Planets.Sun, Planets.SouthNode, orbits));
//Output: Conjunction

Console.WriteLine(chart.AspectBetween(Planets.Moon, Planets.SouthNode, orbits));
//Moon: None

// Will throw NotSupportedException, because Jupiter is not given in orbit table.
Console.WriteLine(chart.AspectBetween(Planets.Jupiter, Planets.Sun, orbits));

The structure of the json needs to look like this:

{
  "aspect": {
    "planet": 123,
    "planet": 123,
    ...
  },
  "aspect": {
    "planet": 123,
    "planet": 123,
    ...
  },
  ...
}

The mapping to the enums is listed in the table below:

Visualizing a chart

SharpAstrology offers a package that allows you to visualize your AstrologyChart via a Blazor component. See the project SharpAstrology.West.BlazorComponents.
