Traditional Chinese texts do not always say “Zi hour” or give a number. They may name the felt stage of the day: yeban for midnight, jiming for the rooster’s call, richu for sunrise, huanghun for dusk, or rending for the time when people have settled for the night.
In brief: A familiar set of 12 day-part names runs from 夜半 (yeban, midnight) through 人定 (rending, settled night). The names pair naturally with the 12 shichen, but they began as observations of darkness, light, meals, work, animals, and social rhythm—not as digital timestamps.

The twelve names and modern times
| Shichen | Modern reference | Traditional day-part name | Plain-English sense |
|---|---|---|---|
| Zi (子) | 11 p.m.–1 a.m. | 夜半 (yeban) | Middle of the night |
| Chou (丑) | 1–3 a.m. | 鸡鸣 (jiming) | Rooster call |
| Yin (寅) | 3–5 a.m. | 平旦 (pingdan) | Level dawn / before sunrise |
| Mao (卯) | 5–7 a.m. | 日出 (richu) | Sunrise |
| Chen (辰) | 7–9 a.m. | 食时 (shishi) | Meal time |
| Si (巳) | 9–11 a.m. | 隅中 (yuzhong) | Sun nearing mid-sky |
| Wu (午) | 11 a.m.–1 p.m. | 日中 (rizhong) | Middle of the day |
| Wei (未) | 1–3 p.m. | 日昳 (ridie) | Sun past its height |
| Shen (申) | 3–5 p.m. | 晡时 (bushi) | Later meal time |
| You (酉) | 5–7 p.m. | 日入 (riru) | Sunset |
| Xu (戌) | 7–9 p.m. | 黄昏 (huanghun) | Dusk / twilight |
| Hai (亥) | 9–11 p.m. | 人定 (rending) | People settled for the night |
The modern times follow the standard branch-hour conversion published by the Hong Kong Observatory. The day-part pairings and literary examples are summarized by a cultural essay from China’s Central Commission for Discipline Inspection and National Supervisory Commission (“The Twelve Shichen in Tang and Song Poetry”).
English translations vary because several names describe a condition rather than a clock unit. Pingdan can be rendered as dawn, daybreak, or the time before sunrise. Ridie is the sun declining from its highest position, not a single universally fixed minute.
What the names reveal about daily life
The sequence turns a day into observable events.
Night is heard as well as seen
Jiming means rooster call. Before personal clocks, recurring sounds helped people locate themselves in the night. Later cities also used watchmen, bells, drums, and official signals. The name does not mean every rooster called at precisely the start of modern Chou hour; it makes an environmental cue into a shared temporal expression.
Morning and evening follow light
Richu is sunrise, riru is sunset, and huanghun is twilight. Actual sunrise changes with latitude and season, while the modern branch-hour table remains fixed. A reader should therefore distinguish the image carried by a word from a modern conversion used for convenience.
Meals become time markers
Shishi and bushi refer to eating periods. They preserve a social rhythm in the vocabulary itself. They should not be turned into a universal claim that every class, region, and historical period ate on exactly the same schedule. Court officials, farmers, soldiers, merchants, and monastic communities could organize work and food differently.
Night ends when people settle
Rending literally evokes people becoming settled or still. It describes a social condition more vividly than “10 p.m.” The phrase can carry quiet, closure, security, or suspense depending on the text.
How to read the names in literature
When a poem says yeban, the first question is not “Was it 12:00 exactly?” Ask what the time word is doing in the scene:
- Setting light: sunrise, declining sun, twilight, or darkness.
- Setting sound: rooster call, bell, drum, watch beat, or silence.
- Setting activity: eating, traveling, opening, closing, watching, or sleeping.
- Setting emotion: anticipation before dawn feels different from settled night.
A translator can choose among three strategies:
- retain the Chinese term and explain it once;
- translate the day-part image, such as “at dusk”;
- add an approximate modern range when timing affects the plot.
The best choice depends on the text. A historical thriller may need the countdown; a poem may lose more than it gains if huanghun becomes “7:32 p.m.”

Why the clock conversion is approximate
The 12 equal two-hour ranges are extremely useful for modern readers, but historical timekeeping included more than one system. Water clocks measured controlled flow; gnomons and sundials referred to the Sun; night watches responded to the length of darkness; officials announced time through sounds and placards.
Recent scholarship on late medieval Chinese astronomical institutions emphasizes that timekeeping continually referred to natural and seasonal conditions, even where officials used sophisticated calculations and instruments (Journal of Chinese History).
Use the table as a reading aid:
- branch time gives a conventional two-hour window;
- the day-part name gives environmental or social texture;
- the specific source supplies the historical context.
Frequently asked questions
What is the traditional Chinese word for midnight?
Yeban (夜半), literally the middle or half of the night, is paired with Zi hour in the familiar 12-part sequence. Ziye (子夜) is another common expression for midnight.
What does rending mean as a time?
Rending (人定) evokes the time when people have settled for the night. It is associated with Hai hour, conventionally 9:00–11:00 p.m.
Is huanghun exactly 7 p.m.?
No. Huanghun means dusk or twilight. It is paired with Xu hour in the conventional table, but lived twilight changes by season and location.
Why is rooster call between 1 and 3 a.m.?
The name jiming is traditionally paired with Chou hour. It should be read as a cultural time cue, not a claim that all roosters follow a standardized clock.
Are these the only historical Chinese time names?
No. Chinese texts contain additional synonyms, local expressions, administrative units, watch terms, and period-specific systems. These 12 form a particularly memorable day-part sequence.
Reading a day as light, sound, and activity
The twelve names preserve what a numbered clock tends to hide: midnight has depth, dawn arrives in stages, meals organize work, the Sun declines, and a community grows quiet.
