That night, Minjun wrote in his journal: Winter in Korea starts three times—by tradition on November 7 or 8, by astronomy on December 21 or 22, and by weather on December 1. But for Harabeoji, it starts the moment you put on your first pair of long underwear and hear the ajummas on the street say, ‘It’s really cold now.’
His grandfather smiled. “No. Winter starts when you decide to notice it. In Korea, it arrives like a quiet guest—first as a whisper in November, then as a promise in December. But if you really want one answer for your friends?” He tapped Minjun’s notebook. “Tell them: meteorological winter in Korea begins December 1. That’s what weather forecasters use. Average temperatures drop below freezing, and the first snow usually falls in Seoul around mid-December.”
He underlined the last sentence: That was November 18 this year. And I think that’s the real answer. when does winter start in korea
Then, on December 22, they stood on a bridge over the Han River in Seoul. The thermometer read minus six Celsius. “And today,” Harabeoji said, “the sun reaches its lowest point. From now, the light slowly returns. That is also winter’s beginning.”
In Korea, the answer to “when does winter start” depends on who you ask—and that small question once sparked a quiet, unforgettable moment between a grandfather and his grandson. That night, Minjun wrote in his journal: Winter
Instead of answering, his grandfather took him on a weekend trip to the old village. On November 8— Lidong —they woke before dawn. The old man pointed to the persimmon trees, dried and hanging with orange fruit like little suns. “See? The birds are already fluffing their feathers. The air smells of frozen earth. This is when we say winter has entered.”
His grandfather explained: according to the lunar calendar, winter begins around the start of Lidong (입동)—usually November 7 or 8. That’s when farmers traditionally prepared kimchi and stored root vegetables. But by the solar calendar used in schools, winter began at the solstice. And by feeling? Winter in Korea truly starts when the first Siberian wind sweeps down from Manchuria, usually in late November, turning the golden ginkgo leaves to dust overnight. Winter starts when you decide to notice it
Minjun thought for a long time. Finally, he said, “So winter starts twice?”
