Reviewed definition
Sexagenary Cycle (六十甲子) is a technical term within feng shui and Yijing-related knowledge systems. Specifically, The sixty Stem-Branch combinations running from Jiazi to Guihai and repeating in traditional year and day notation. Feng shui and date-selection systems also incorporate selected pairs into temporal or directional calculations. This library explains it within the calendrical and temporal systems domain and distinguishes historical description, lineage rules, observable spatial data and later symbolic interpretation.
Historical context
The modern meaning of this term accumulated through classical texts, commentaries, regional practice and later systematization. Review used “Heavenly Stems and Earthly Branches” for historical, textual or material context; that source does not establish that every later lineage uses the term identically.
Modern-use note
Today, Sexagenary Cycle may be used in terminology teaching, source indexing, case annotation, compass or landform documentation and comparison of lineage rules. Professional records should state edition, directional reference, scale, date, observations and uncertainty so another reader can trace the reasoning.

Limitations and cross-cultural caution
This term records a cultural, historical or lineage-specific interpretive framework. It must not be presented as established scientific causation or a guarantee of health, wealth, relationships, examinations or investment outcomes. Building, structural, fire, environmental, medical, legal and financial matters require applicable rules, measurements and qualified advice.
Cross-cultural writing should retain 六十甲子 with a transliteration or conventional translation. Japanese “六十干支”, Korean “육십갑자” and English “Sexagenary Cycle” may have different local ranges; similar labels do not make methods, historical authority or practical conclusions identical.
