Korean lunar birthday converter: this year's date
Enter a lunar birthday or memorial day. Get this year's and next year's solar dates, days left, and a calendar file for every year.
A Korean lunar date lands on a different solar date each year, so families look up a parent's birthday or a jesa (ancestral memorial rite) date again every year. Enter it once and see this year and next year together, plus a calendar file with one event per year through 2050.

Dates come from a lunar conversion table that follows the Korea Astronomy and Space Science Institute (KASI) standard. We checked 37 dates one by one against KASI's own converter. Where families differ, as with leap months and day 30, we don't decide for you and show both dates.

Add every year to your calendar
One event per year from this year through 2050. A single repeating event won't work because the solar date moves each year.
Reminders live inside the file and your phone's calendar rings them. We don't send notifications.
