Calculation guide

Birth profile

Enter the date and ordinary local clock time at the birthplace. Select the birthplace IANA time zone, for example Europe/Prague. The website converts local time to UTC using the rules for that date; do not add daylight saving time manually.

Map coordinates are usually given as latitude, longitude. The current residence requested by some reports is separate from the birthplace.

If the birth time is unknown, do not treat houses and time-sensitive points as certain. Entering an approximate time does not make it historically known.

Birth chart

First check the birth date, clock time, time zone and birthplace. Then run the chart calculation.

The graphical and text output use the same input. Opening a completed result in a new window is for reading it, not for starting another calculation.

Daily influences

Choose the day to calculate. Birthplace and current residence are separate inputs; location-dependent parts of the output require the correct residence.

Rows contain calculated events and accompanying texts. These are astrological interpretations, not verified predictions of events.

Online reports

Each report has its own description and range. Some refer to a selected day, others to a month or longer period; the date does not have the same meaning for every report.

Read the selected report description before running it. If the output differs substantially from what you expect, check the input time, time zone, coordinates and report type first.

AI data

The sports tool creates a prompt and one JSON object for the specified match. Before copying it, check both birth dates, whether each birth time is known, the match time zone and the odds.

An AI can use the supplied JSON but should not invent missing facts. A documented API is available for individual planetary positions; planetary positions cannot guarantee a match outcome.
