GUIDE

How to use it

Built-in person data

The selector is limited to widely verifiable lifespans: Sejong (1397-1450), Yi Sun-sin (1545-1598), Isaac Newton (1643-1727), and Marie Curie (1867-1934). It calculates year-level age only, not birthday-precise age.

Source check

For reports, re-check lifespans in authoritative entries such as Encyclopedia of Korean Culture, Encyclopaedia Britannica, or Nobel Prize biographies. Calendar-change periods can shift exact date-based ages.

Frequently asked questions

Does it verify historical facts automatically?

No. This first slice uses input-based calculations and a small reviewed static dataset only.

Can I cite the result directly?

Use it as a reference and verify with primary sources or authoritative references for academic or official work.
