GeoNames
Place names, coordinates and time zones offered by the birthplace search come from GeoNames, used under the Creative Commons Attribution 4.0 licence. The data was filtered and bundled with the app, so no search leaves your device.

Sources of the tradition
The planetary hours follow the Chaldean order; the angels follow the Shem HaMephorash as given by the Golden Dawn tradition; the tarot attributions follow the Golden Dawn paths of the Tree of Life. These are public tradition; their arrangement and weighting in Siderarium are proprietary.
