About, Methodology, and Editorial Standards
Read how Lucky By Birthday calculates Saju pillars, separates calendar facts from interpretation, reviews editorial content, and communicates limitations.
Who publishes this site and how to check it
Page updated:
Lucky By Birthday publishes an introductory calendar tool and cultural guides. The publisher is responsible for corrections. The site does not claim accreditation as a professional Saju practitioner or endorsement by the institutions linked below.
AI assists with guide drafting, translation, and code. The default chart and weekly numbers are calculated on your device and accompanied by a prepared general reflection. Only a separate, optional AI request generates a chart-based reflection; that response is not individually reviewed before delivery. A content revision date records a site update, not an independent expert certification.
The methodology page provides a ten-date comparison against the Hong Kong Observatory’s 2026 Gregorian–Lunar table. This checks lunar date conversion only. It does not independently validate all four pillars, historical timezones, or predictions.
Calendar calculations use the public lunar-javascript library, not an independently developed engine. The site adds its own interfaces, counting rules and explanatory experiments. Same-library examples are distinct from external reference checks. Corrections should include the page URL, disputed statement and a specific source, not private birth records.

What changed
Reworked three existing guides into a searchable symbol reference, a sixty-pair cycle explorer and two worked Day Master/count comparisons. Reduced repeated editorial notes and organized the guide index by reader task. No new personal data collection or chart-accuracy certification.
Added a local chart-discrepancy workbench with raw counts, targeted checks, a downloadable comparison record and three reproducible experiments. Replaced the repeated hub lesson and corrected calendar-library attribution. These are same-library demonstrations, not independent certification.
Enabled the published general and privacy email forwarding addresses, aligned contact links and page dates, and clarified email processing and optional AI use. This change does not certify chart accuracy or guarantee email delivery.
Moved the default chart and weekly numbers to on-device calculation. AI reflection now requires a separate button, and a previous-week comparison shows recalculated numbers rather than a saved visit history.
September 30, 2026 · Reading experience revision
Removed result scores and predictive health/finance sections, separated calendar values from creative interpretation, added five practical reflection activities and an optional device-only record, and replaced the page-load alert with an importable calendar reminder. The weekly clock now uses Sunday 00:00 KST consistently. Birthplace/time-zone corrections remain unsupported.
