"Noon" is generally between 1 1 and 13. At 3 noon, near 12, the sun hangs in the center of the sky, which is the shortest shadow on the ground. At that time, in people's eyes, "Yang" was the peak in a day.
Extended data
In ancient times, starting from the Tang Dynasty, twelve o'clock was divided into two parts, the first part and the second part. A third of noon is a third of noon (not a third of noon). However, the noon of the last quarter is not the time when the sun is at its peak. The closest time is the noon of the last quarter, and now it is 1 1 point 45.
