Astronomical knowledge travels through connected regions

Tracking lunar phases, seasons and solar turning points helped coordinate ceremonies and agricultural time.

Its chronology and interpretations should be read as scholarly arguments rather than uncontested conclusions.

The exact date belongs to the modern study, not to the much older developments it analyzes.

The paper examines similarities in lunar divisions, calendars, zodiacal schemes and year lengths.

The author rejects an automatic assumption that every shared feature proves one-way borrowing.

Similar concepts may arise independently, be borrowed selectively or be transformed through local practices.

The publication shows why ancient eclipse observations cannot be matched accurately without accounting for changes in Earth's spin.

Mesopotamian scholars recognized repeating relationships in lunar eclipses and passed this numerical knowledge into later traditions.

Comparing historical reports with Newtonian calculations revealed that the Moon's apparent motion could not be treated as perfectly uniform.

Long-term tidal interaction between Earth and Moon gradually changes day length and shifts reconstructed eclipse paths.
