How this service works
Deterministic Western + Vedic astrology API for AI agents: JPL DE440 ephemeris, no LLM, reproducible SHA-256 hashes.
Output
Returns a JSON object containing the resolved UTC datetime, timezone identifier, UTC offset, Julian Day UT, Delta-T in seconds, true solar time, and a SHA-256 hash of the result for reproducibility verification. Also includes engine metadata confirming no LLM was used and the ephemeris version.
Example use cases
Birth chart time normalization
“I need to calculate an astrology birth chart for someone born on March 21, 1985 at 3:15 AM in Chicago — can you resolve that civil local time to UTC and Julian Day so I can feed it into the planetary position calculator?”
Historical event astronomical time
“What was the Julian Day number and true solar time for the moment of Indian independence on August 14, 1947 at 11:30 PM at latitude 28.6139, longitude 77.2090 in Asia/Kolkata timezone?”
Ambiguous DST time resolution
“I have a birth time of November 1, 2020 at 1:30 AM in New York (latitude 40.7128, longitude -74.0060) that falls in the ambiguous daylight-saving overlap — please resolve it using the earlier occurrence and give me the UTC time and Delta-T.”
Technical details
Endpoint
POSThttps://astro-agents-api.vercel.app/v1/time/resolve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, reproducible conversion of a civil, LMT, or true-solar datetime to UTC and Julian Day — especially for astrology or astronomy calculations requiring Delta-T and true solar time. Prefer it over general timezone APIs when you need Julian Day UT, Delta-T, and SHA-256 result hashing for auditability, and when working with historical dates or non-standard time bases like local mean time or true solar time.
Side effects
- Missing required fields (date/time or datetime) returns validation error
- Latitude or longitude out of range (-90 to 90, -180 to 180) returns schema error
- Invalid or unrecognized timezone string causes resolution failure
- Datetime outside ephemeris range (1800-2200) may return out-of-range error
- Ambiguous time without specifying ambiguous_time enum may default to 'earlier' silently
