Dotori Date & Lunar Calculator
com.droidactor.lunar
Convert Korean lunar dates, compare three ages and calculate Korean business days on your phone.
Solar and Korean lunar dates
Convert both ways, including leap months, and find the next solar date of a lunar birthday or memorial. Solar range: 1900-01-01 through 2050-12-31.
Ages and date ranges
Compare full, year and Korean ages with a Lunar New Year zodiac. Count calendar days and business days, choose start inclusion, move 100 days or one year and add extra holidays.
Scope
Business-day range: 2023–2050, up to 3,660 days. Known one-off holidays through 2026 are included; future years follow current rules. Add newly announced holidays manually. Missing lunar day 30 is skipped; leap-month anniversaries have a regular-month option. The app does not determine legal eligibility or every employer’s leave policy.
Privacy
Birth dates, conversion inputs, date ranges and extra holidays are processed on the device and are not sent to a developer server or ad SDK. Drafts use Android saved screen state; theme, language and orientation preferences stay local. Automatic backup and device transfer are excluded. There is no account, sign-in, calendar or location permission. Google AdMob/UMP and Play updates may use the network. Under available privacy choices, advertising may process IP-derived approximate location, ad interactions, diagnostics and device identifiers. Reopen available choices in Settings. Clear app data or uninstall to remove local preferences.
