Direct answer
Light-Time Correction accounts for the finite interval required for light to travel between an event, observer, and reference point.
It aligns an observed signal with its emission geometry.

The story behind Light-Time Correction
Increasing timing precision made finite light travel an operational correction rather than a curiosity.
Light-Time Correction in spiritual tradition
Even observation is a meeting with the recent past.
The Great Almanac frames Light-Time Correction with educational restraint. Mystical or symbolic language may be meaningful, but it should not be exaggerated into certainty, panic, or permission to ignore ordinary responsibility.
Light-Time Correction in the Bible
This is a factual astronomy reference. It can support wonder at the created order without becoming a claim of fate, worship, or private revelation.
Light-Time Correction in numerology
Light-Time Correction is not a numerology claim. Any numbers attached to it should retain their ordinary scientific, calendrical, navigational, or historical meaning unless a separate symbolic interpretation is clearly labeled.
Why Light-Time Correction matters
It is essential when positions or periodic events require precise timing.
Example in a reading: A planetary observation records where the planet was when its light departed, not at reception.
Interpretive caution: Do not apply one correction indiscriminately to every reference frame.
How Light-Time Correction is used in a reading
Use the appropriate geometric, heliocentric, or barycentric correction for the task.
Where interpretation stops
Light-Time Correction is presented as sourced astronomy, calendrical, Earth-science, cultural, or instrument-history reference. Definitions should distinguish measured phenomena from civil convention and historical interpretation, preserve location and time dependencies, and avoid turning factual sky data into a deterministic personal claim.
Sources and editorial method
Research references used for this entry include:
- U.S. Naval Observatory: Astronomical Almanac Glossary - Definitions for astronomical coordinates, time, reference systems, and observable phenomena.
- International Astronomical Union: Standards of Fundamental Astronomy - IAU-maintained standards and algorithms for astronomical reference systems and coordinate transformations.
The page starts with a direct definition, then separates use, example, caution, spiritual meaning, and historical context. For astrology, occult, demonology, curse, and spiritual warfare terms, the editorial rule is to explain the term without making fear-based, fatalistic, medical, legal, financial, or ritual-instruction claims.
