When is the third quarter?

In ancient times, one day and night was divided into 100 minute, and three minutes is equivalent to 45 minutes today. Take the common "three minutes at noon" as an example. Since the Tang Dynasty, twelve o'clock has been divided into two parts, that is, three points at noon, that is, three points at noon (not three points at noon). However, the three minutes at noon are not the time when the sun is the strongest, and the closest time is the three minutes at noon, which is now 1 1 45.

Extended data:

At 3: 30 noon, the sun hangs in the middle of the sky, which is the shortest shadow on the ground. At that time, people thought it was the peak of yang in a day. In ancient China, people were superstitious that killing people was a "dirty thing", regardless of whether the person who was killed deserved it;

His ghost will haunt the minds of the judge who sentenced him, the official who supervised the execution, the executioner who executed him and those related to his execution forever. Therefore, the execution of the death penalty at the peak of Yang Can will inhibit the appearance of ghosts. This should be the main reason why the ancients used to execute at "three quarters at noon".
