Korea runs on the solar calendar day to day, but the big family holidays still follow the moon. In 2027 the two that matter most are Seollal (설날), Sunday, February 7, and Chuseok (추석), Wednesday, September 15. Plenty of Korean families, especially grandparents, also keep birthdays by the lunar calendar, which moves every year.
Here’s the 2027 lunar calendar the Moon Rabbit uses, plus how to work out a lunar birthday and how lunar dates fit into a saju chart.
Lunar holidays in 2027
| Holiday | Lunar date | Solar date in 2027 | Public holiday in Korea? |
|---|---|---|---|
| Seollal (설날, Lunar New Year) | 1st month, 1st day | Sunday, February 7 | Yes, February 6 to 8 |
| Jeongwol Daeboreum (정월대보름, first full moon) | 1st month, 15th day | Sunday, February 21 | No |
| Buddha’s Birthday (부처님오신날) | 4th month, 8th day | Thursday, May 13 | Yes |
| Dano (단오) | 5th month, 5th day | Wednesday, June 9 | No |
| Chilseok (칠석) | 7th month, 7th day | Sunday, August 8 | No |
| Chuseok (추석, harvest festival) | 8th month, 15th day | Wednesday, September 15 | Yes, September 14 to 16 |
Seollal and Chuseok are three-day holidays: the day before, the day itself and the day after. Seollal 2027 falls on a Sunday, and Korea’s substitute-holiday rule usually adds a weekday off when that happens, so expect one more day after the break. Confirm with the official calendar closer to the date.
There’s no leap month in the Korean lunar calendar in 2027, so every lunar date appears exactly once this year.
Why Seollal 2027 isn’t the same day as Chinese New Year
Chinese New Year 2027 is Saturday, February 6, a day before Seollal. The lunar month starts on the day of the new moon, and in February 2027 the new moon arrives just after midnight in Korea, which is still just before midnight in China. Korea’s lunar calendar is calculated for Korea time, so the date shifts by a day. The Chinese New Year 2027 post has the full story.
The same thing can happen with other lunar dates. If you’re converting a birthday, use a calendar made for the country where it was recorded.
How to find your lunar birthday in 2027
A lunar birthday stays fixed on the lunar calendar and moves around on the solar one. To find it:
- Convert your birth date to lunar. For example, someone born on the solar date March 10, 1990 was born on the 14th day of the 2nd lunar month.
- Find that lunar date in 2027. Look up the 2nd month, 14th day of the 2027 lunar calendar, and that’s the day to celebrate.
- If you were born in a leap month, note it. Leap months don’t come back every year, so most families celebrate in the regular month with the same number.
Older Koreans often know their lunar birthday better than their solar one, which is why forms in Korea sometimes ask which calendar a birthday is in.
Lunar dates and saju
Saju charts don’t actually run on the lunar calendar. The year changes at Ipchun, around February 4, and months change at solar terms, which follow the sun. The lunar calendar comes in only at the start: if you know your birthday as a lunar date, a calculator converts it to the solar date first.
That’s why SajuBunny’s free saju calculator has a lunar option with a leap-month box. Choose Lunar, enter the lunar date, tick Leap month if it applies, and the chart is worked out from the converted solar date. It uses the Korean lunar calendar by default for English and Korean, and the Chinese one for Chinese.
A lunar birthday also doesn’t change your zodiac animal on its own. People born in January or early February often have a different sign depending on whether you count from the lunar new year or from Ipchun; the zodiac years chart lists both dates for recent years.
