Keep track of the people and dates that matter.
Find every exact lunar birthday in one or several Gregorian years.
Calculate completed years and the next Gregorian anniversary.
Keep the original leap-month birthday intact, check exact annual matches, and record a separate family celebration decision when no match exists.
Check the actual Chinese lunar month length, distinguish a missing day from a missing month, and keep celebration choices separate from exact conversion.
Understand the search window, verify both lunar years, and distinguish annual birthday matches from the next reminder or a person's age.
See how the calculator uses 1 March in non-leap years, compare worked age examples, and keep personal celebrations separate from formal eligibility rules.
Keep original birth records, Chinese lunar details, annual matching dates and celebration plans separate so reminders can be checked and updated reliably.
