His grandfather, who grew up in a mountain village near Sokcho, chuckled softly. “In my heart,” he said, “winter starts the first morning you see your breath freeze in front of you. But officially? Korea has two winters.”

Twelve-year-old Minjun lived in Seoul, where his science teacher had just taught him the astronomical seasons: winter begins on the winter solstice, around December 21 or 22.

His grandfather explained: according to the lunar calendar, winter begins around the start of Lidong (입동)—usually November 7 or 8.

Minjun thought for a long time. Finally, he said, “So winter starts twice?”

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.”
