How to use Lunar and Solar Date Converter
Use the browser's Korean Dangi calendar to convert a solar date to lunar or a lunar date with leap-month status to solar within 1900–2100.
The result pairs the solar date with lunar year, month, day, regular or leap month, and a sexagenary-year label when available. Verify important dates with KASI.
- Choose solar-to-lunar or lunar-to-solar direction.
- Select one solar date, or enter lunar year, month, day, and the correct leap-month setting.
- Review the paired dates and month type, then compare important results with the linked official converter.
Useful for
- Record both calendar forms for a family birthday or memorial date.
- Check regular-versus-leap-month details before adding a recurring calendar event.
Limits and checks
- A regular and leap lunar month can share the same month number, so the leap-month checkbox matters in reverse conversion.
- An impossible day, such as day 30 in a shorter lunar month, may have no matching solar date.

FAQ
Why can lunar-to-solar conversion take longer?
The tool searches supported solar dates until it finds one whose lunar year, month, day, and leap status all match.
Can I use the result in an official record without checking?
Treat it as a browser-calendar reference. Verify dates that affect filings, contracts, ceremonies, or reservations with KASI and the responsible institution.
