How this is calculated
Geocentric positions in the tropical zodiac, computed from deterministic ephemerides — the same calculation an astronomer uses, never estimated by a language model. Given at 12:00 UTC, the standard convention for a date without a time. Houses and ascendant are not published: they depend on the birth place, which a single-day ephemeris does not have.
The Moon travels about 13° per day, so its noon position carries a ±6.5° margin against the extremes of that day. An exact figure for a moment needs the time.
