What is Lunar Birthday & Hwangap Calculator?

For someone whose birthday falls on the lunar calendar — like a parent — this tool finds “which solar date their birthday lands on this year,” and even computes big celebration days such as the 60th, 70th, and 80th birthdays at once. A lunar birthday shifts to a different solar date every year and is easy to forget, and these milestone feasts (suyeon) need their dates known in advance to prepare. Just enter the lunar date of birth and it lays out this year's solar date and the upcoming celebration days.

How it works

1 Enter the lunar date of birth of your parent (or yourself). If they were born in a leap month, select that as well.
2 This year's solar birthday is calculated right away. Save it to your phone calendar so you never miss it.
3 Also check the solar dates of milestone feasts — hwangap (age 60), chilsun (70), palsun (80) — to plan the celebration in advance.

Frequently Asked Questions

If someone was born on lunar April 24, 1960, when is their solar birthday this year? ⌄

Enter the lunar date of birth and it precisely calculates this year's solar date matching that lunar date. You do not have to look up the ever-shifting solar birthday yourself.

How old are hwangap, chilsun, and palsun? ⌄

Hwangap (hoegap) is age 60 — the year the birth ganji has come full circle — chilsun (gohui) is 70, and palsun is 80. The calculator tells you the solar year and date for each age.

Is it accurate for someone born in a leap month? ⌄

Yes. You can select the leap-month flag, so a leap-month birthday converts accurately to solar. If plain vs. leap month is unclear, we suggest checking with a family elder.

Does it also convert lunar dates like ancestral rites? ⌄

Yes — beyond birthdays, you can use it to find this year's solar date for lunar-calendar ancestral rites and death anniversaries. For general lunar-solar conversion, also use the “Lunar ↔ Solar Calendar Converter” tool.
