Sidereal · Swiss Ephemeris

Birth chart generation with a strict pipeline: birth data → historical timezone → Swiss Ephemeris → sidereal conversion → Parashari rules → JSON → interface. The browser performs no astronomy.

Birth data

All calculations run server-side on the Swiss Ephemeris.

Pick a city to fill the coordinates, or type any place and enter them by hand.

North and east are positive.

Historical offsets are resolved for the birth instant, not today — Nepal correctly uses +05:30 before 1986 and +05:45 after.

Engine configuration

The benchmark reproduces on the mean node. See SPEC.md for why the source document’s prose disagrees with its own numbers.

Enter birth data and generate a chart.

The form is pre-filled with the golden benchmark case — 13 June 2000, 10:00 NPT, Kathmandu.
