When is the sun at noon on weeding day?

It's noon on weeding day, but the summer of solstice hasn't come yet. The summer solstice refers to the day when the sun reaches 90 degrees of the yellow meridian, which is the longest day in the earth's revolution for one and a half years, generally around June 2 1. Because the sun is at its highest point in summer solstice, the sun is also the highest and the light is the strongest at noon on weeding day. Therefore, in most cases, the sun at noon on weeding day refers to the period from summer to around, and the specific time may vary from region to region, but it is all around June.
