The vernal equinox solar terms in the northern hemisphere and the length of day and night in Qingdao are as follows

Hello, the vernal equinox solar terms in the northern hemisphere are on March 2 1 every year. Theoretically, on this day, the sun shines directly on the equator, and the whole world is divided equally day and night. Of course, Qingdao was in the early days of the earth, so it also followed this law. Therefore, the solar terms of the vernal equinox in the northern hemisphere are equally divided day and night in Qingdao (sunrise around 6 am and sunset around 18 pm).

This has nothing to do with longitude ~
