From the Korea AeroSpace Administration’s calendar for 2027, published on 29 June 2026: chobok on Tuesday 20 July, jungbok on Friday 30 July and malbok on Monday 9 August. None of the three is a public holiday. The 2028 days can be calculated, but they are listed here only once the next calendar is published, around June 2027.

Boknal are the three days that mark the hottest stretch of the Korean summer, and on each of them Seoul eats samgyetang, ginseng chicken soup, brought to the table boiling in a stone pot. The idea is that heat drives out heat. For a visitor it is the easiest way into a Korean custom there is: join the lunchtime line at a samgyetang restaurant and you are doing exactly what the office workers around you are doing. The catch is the line, which at the best-known restaurant near Gyeongbokgung can run down the street.

What Boknal actually is

The three days, chobok, jungbok and malbok, open, mark the height of and close the dog days of summer. They are set neither by the modern calendar nor by the moon but by a ten-day count from the old sexagenary calendar, reckoned from the summer solstice and from the solar start of autumn, so they move from year to year and fall ten or twenty days apart. The national calendar lists them each year alongside the public holidays.

They are not holidays. Offices and shops stay open, and the custom is simply what people eat. Samgyetang is the classic: a small chicken stuffed with sticky rice, ginseng, jujube and garlic, simmered whole and often served with a small glass of ginseng liquor. Duck and grilled eel are the other boknal dishes, and dog-meat soup, once part of the custom, is disappearing under a national ban on the trade.

Tickets and what it costs

Nothing needs booking. A bowl at a well-known Seoul restaurant costs around ₩20,000, a little more for the versions with black-skinned chicken or extra ginseng. What boknal adds is the wait.

Getting there

For Tosokchon, take Line 3 to Gyeongbokgung station and walk into the lanes on the west side of the palace. It opens at ten in the morning and closes at ten at night, with last orders an hour earlier.

Boknal falls in the hottest, most humid weeks of the year, and the first of the three often lands in the monsoon. Queue with water and an umbrella, which serves for sun and rain alike, and keep the sightseeing for the morning and the evening.
