The certificate, from the inside
Every order arrives with a separate document stating what the chart was computed from. This is a real one, with sample data: open any field to see what it means and why it is there.
Certificate
NameAmaia
The name printed on the piece when you choose to show it, and the one that tells each chart apart when there is more than one.
Date and time2026-08-04 · 01:26
The time fixes the ascendant and the house division. Without it the chart is still right about signs and planets, but the houses stop being yours.
PlaceBilbao
The declared place, as it resolved. If the geocoder cannot find the city it does not invent one: the order does not proceed.
Coordinates43.2630° N, 2.9350° W
The real latitude and longitude of the place, in degrees with hemisphere. These are what enter the calculation, not an approximation to the country.
Time zoneEurope/Madrid
The IANA zone in force that day, with its daylight saving if there was any. It is the step where most charts go wrong, which is why it is written down.
House systemplacidus
Placidus by default. Changing it changes where the houses are cut: two charts of the same moment under different systems are not the same chart.
Zodiactropical
Tropical by default: signs are measured from the equinox, not from the constellations.
Sample data. On your order every field resolves from yours.
