Why didn't the dawn come earlier after the winter solstice? The solstice in winter is the shortest day in a year.

From the perspective of astronomy and geography, the winter solstice is the lowest day of the sun in the northern hemisphere, and it is also the shortest day of the year in the northern hemisphere. The farther north, the shorter the day is. North of the Arctic Circle, the sun is below the horizon all day, which is the widest day of the year in the northern hemisphere.

Simply put, on the day of winter solstice, the sun shines almost directly on the tropic of Capricorn, and the northern hemisphere will experience the shortest day and the longest night in a year. From winter to the future, direct sunlight gradually moves northward, and the days gradually become longer until the summer solstice (the longest day in the northern hemisphere).
