How did ancient people judge time?

Using a leaky pot is to judge the time by leaking rice downward. Satisfied.

1.Sun: In ancient times, the sun rose and rested, that is, by looking at the sun in the sky to judge the time, the sun is above the head is noon, the sun goes down is to the evening, this method is very rough, I don't know the specific time.

2.The sundial, much like our current clocks, was made up of hands and discs, but its hands were made of copper and the discs were made of stone. The sundial is to use the length and direction of the sun's shadow to judge the time, so the shadow is called time, the ancients compared time to time, and now the meaning of an inch of time refers to an inch of shadow on the sundial.

As the water flows down the small hole in the bottom of the pot, the water level in the pot gradually drops, and the wooden arrow drops along with the water level. Then you just need to look at which tick mark the arrow of the wooden arrow is pointing to know what time it is.

4.Incense clock: a very convenient fire clock, with a special mold made of incense, the thickness of the incense is uniform, the burning time is proportional to its length, that is, the longer the burning time, the less remaining incense.

Write down the scale on the incense plate to know the time of the phase change. There is also an incense clock with an alarm clock function, when the incense burns to a fixed scale, the heavy objects hanging on it will fall and hit the metal utensils, and then make a ring, used to remind others, playing the role of an alarm clock.

5.Incense timing: It is by lighting a stick of incense, and when it burns out, it is the time of a stick of incense, and the time of a stick of incense is half an hour.

Sundials are not easy to use on cloudy days and at night, they are affected by the weather, and if it is rainy, it is also impossible to measure the time. Although the leaky pot is not affected by day and night, sunny and rainy days, the speed of its dripping is affected by the temperature, that is, there is an error in the timing in summer and winter.

In ancient times, there were errors in the way of timekeeping, and now you can look at the time at hand, and you can look at the mobile phone directly, because it is networked, there will be no error.

In ancient China, there were sundials (gui, the third tone), water clocks, fire bells, copper kettle dripping and other timers.

In ancient China, people invented many methods or tools for keeping time. The gui (pronounced guī) table is a simple and important instrument for measuring the heavens, which consists of a vertical table (usually eight feet high) and a horizontal gui table. It uses the principle of immediate results to measure the length of the sun's shadow.

The main function is to determine the location of the winter solstice day and then determine the length of the return year. In addition, by observing the changes in the surface shadow, the direction and solar terms can be determined. The sundial (pronounced guǐ), also known as the "day gauge", is another timekeeping instrument used to measure the time by using the sun's shadow in ancient China.

It usually consists of a copper hand and a stone disc. The copper hands are called "sundial needles", and the stone discs are called "sundial faces". When using, you can distinguish the different times by looking at the position of the shadow cast on the disk.

The sundial is accurate to the quarter (15 minutes). Copper kettle dripping is also known as "leaky carving" or "leaking pot". That is, a water holding tool with a small hole in the bottom of the pot or near the bottom is used to calculate the time by using the flowing water from the orifice to change the water level of the copper kettle.

The copper kettle drip invented in China is much earlier than the drip timer made in foreign countries, and it is widely used and has become an important tool for timekeeping in the past dynasties. In addition to the above timing methods, ancient Chinese people also used "hourglass", "fire timing", "candlelight timing" and other methods to keep time.
