Lunar-Solar Calendar Converter
The Korean lunar calendar still governs birthdays, ancestral rites (jesa) and holidays like Seollal and Chuseok in many families, so people regularly need to convert a date between it and the solar calendar. Enter a solar or lunar date to get the converted date, whether it falls in a leap month, and the sexagenary (gapja) year name. Everything runs in your browser.

Frequently asked questions
- Why would I need to convert to the lunar calendar?
- Many Korean birthdays, ancestral memorial dates and holidays such as Seollal and Chuseok are set by the lunar calendar, so converting to or from the solar calendar is a regular need.
- What does a leap month mean here?
- The lunar calendar occasionally repeats a month to stay aligned with the solar year; the tool marks these leap-month dates so you convert them correctly.
