This is John Harrison's chart for 1776-03-24, the day they died, cast the same way a birth chart is cast. Cast one for any recorded date. It predicts nothing: the date is one you already have.

Their Astrocartography

Where each planet sat on one of the four angles at the moment John Harrison was born. Tap a line to read what the tradition associates with it.

The birth time is unknown, so this map is cast for noon. The SHAPE of it is right and the whole pattern slides east or west with the real time, so treat the longitudes as approximate.

Ten planets on four angles is forty lines, which is more than the interactive tool opens with on purpose. Draw your own map to choose which planets to show.

Charts are computed from real planetary positions (Swiss Ephemeris) for the recorded moment and place. Recorded times can carry small uncertainties; treat house and ascendant placements accordingly.
