Sunrise and sunset time of winter solstice

In most areas of winter solstice, the sunrise time is 07:30 and the sunset time is 16: 30.

The winter solstice is the longest night and the shortest day in a year. Then, in the days near the winter solstice, the sky should become brighter and later. On this day, the sun shines almost directly on the tropic of Capricorn, causing the northern hemisphere of the earth to have the shortest day of the year. Sunrise time is related to latitude and longitude. During the period from the autumnal equinox to the vernal equinox of the following year, the sunrise in high latitudes is later than that in low latitudes, and the daytime is shorter. For example, the latitude of Changchun is higher than that of Shanghai, so the sunrise time in Changchun is later than that in Shanghai during this period.

China attached great importance to the winter solstice in ancient times, and stipulated that the same month as the winter solstice was the "sub-month", which was the first branch of the twelve solar terms. Therefore, the winter solstice is still a traditional festival, commonly known as "Winter Festival" and "Dragon Solstice Festival". In winter, the solstice sun is located in the tropic of Capricorn, with the latest sunrise, the earliest sunset and the shortest day in all parts of the northern hemisphere. However, our sunrise and sunset times are also influenced by the apparent radius of the sun, the eye height difference and the atmosphere. Maybe people think there is no sunset, but it has already set.
