Aurapure's ascendant calculator requires birth date, time, and place. It converts local time to UTC via IANA timezone (historical DST) and calculates rising sign and MC with Moshier ephemeris. Free for basic calculation; personalized report via email with consent. Without birth time the result cannot be determined.

Frequently asked questions
- Why is birth time required?
- The ascendant changes quickly — even a few minutes can shift the sign. Without time we cannot calculate it reliably.
- Which ephemeris do you use?
- Moshier ephemeris (Unlicense) with historical IANA timezones via Luxon. Arcminute-scale precision, independently tested.
- Is it free?
- Yes, the basic calculation is free.
- What is the Midheaven?
- The MC is the southern angle of the chart: public direction and vocation. We calculate it with the ascendant.
- Does daylight saving work?
- Yes. We use IANA zones with historical DST (e.g. Italy before 1966 with no DST).
