It should be the summer solstice, and the day of the summer solstice must be the longest day of the year, usually between June 20th and 22nd.

The 24 solar terms: the spring equinox and the autumnal equinox have equal day and night times.

After the autumnal equinox, the direct point of the sun continues to move from the equator to the southern hemisphere, and the days and nights begin to be shorter and longer in the northern hemisphere, that is, the days begin to be shorter than the nights in a day. The Southern Hemisphere is the opposite. Therefore, the autumn equinox is also called the descending equinox. And at the North and South Poles, on the day of the autumnal equinox, the sun is on the horizon all day.

After that, as the direct point of the sun continued to move southward, a six-month polar night began near the North Pole, and the range gradually expanded and then decreased. A six-month period of polar day begins near the South Pole, gradually expanding and shrinking.

The vernal equinox refers to the position of the sun between 0° and 15° of the yellow longitude, that is, from the day of the vernal equinox to the period before the Qingming Festival, and the Gregorian calendar is about between March 20 and April 5.

In ancient times, the vernal equinox was also called "the middle of the day", "the equinox of day and night", "the moon of mid-spring", "ascending equinox" and so on. The meaning of the vernal equinox is that the time of day is equal to the day and night, each of which is 12 hours; The second is that the spring equinox is in the three months of spring (beginning of spring to beginning of summer), and the spring is equally divided.

The summer solstice is the turning point of the sun, after which it will take a "turning back", the point of direct sunlight will begin to move south from the Tropic of Cancer, and the days will be shorter in the Northern Hemisphere. After the summer solstice, the noon solar elevation angle decreases day by day in the areas north of the Tropic of Cancer and the regions north of it. At the same time, after the arrival of the summer solstice, the night sky and stars gradually turn into a summer starry sky.

The ancients in China divided the 24 solar terms into three phases, that is, "one waits for the antlers to be solved; Second, the cicadas begin to sing; "Three Waiting for Half Summer", which means that at this time of the year, the antlers begin to fall off, the cicadas begin to chirp, and the two plants of Banxia and Hibiscus gradually flourish and bloom.
