Chinese Zodiac Hour Calculator: Find Your Birth Hour Animal Sign
Your birth year gives one Chinese zodiac animal. Your birth time can be read through another traditional layer: the 12 Chinese two-hour periods, or shíchen 时辰.
Enter a birth time to find the traditional Chinese hour, its Earthly Branch, and the zodiac animal connected with that time period.
Find your zodiac hour sign
Use the 24-hour clock. This calculator maps your birth time to the traditional two-hour Chinese zodiac hour. It returns the animal sign, Chinese hour name, Earthly Branch, and modern time range.
This page gives the traditional two-hour zodiac period for a clock time. It is not a complete BaZi 八字 chart. Formal chart work may consider the full birth date, birthplace, time zone, date rollover, and sometimes solar-time adjustments.
What is a Chinese zodiac hour?
In the traditional Chinese time system, a full day is divided into 12 two-hour periods. Each period is called a 时辰 shíchen. Each shíchen is linked with one Earthly Branch and one zodiac animal.
That is why the period from 23:00 to 00:59 is called Zi hour 子时 and linked with the Rat 鼠. The next period, from 01:00 to 02:59, is Chou hour 丑时 and linked with the Ox 牛.
A traditional day has 12 shíchen, not 24 separate animal hours.
Each zodiac hour covers about two modern clock hours.
Each time period has an Earthly Branch and an animal association.
For a broader explanation of the time system, read Chinese Zodiac Hours. For the calendar structure behind the branches, see Heavenly Stems and Earthly Branches.

Why Zi hour starts at 23:00
This is one of the details that surprises English readers. The first traditional hour of the day is Zi hour 子时, and it begins at 23:00, not exactly at midnight. So a time like 11:30 p.m. belongs to Zi hour, the Rat hour.
For a simple zodiac-hour reference, this page maps the clock time to the traditional two-hour branch period. For formal BaZi or Four Pillars work, late-night birth times may raise a separate date-boundary question, and some traditions handle early and late Zi hour with more technical rules.
23:00–00:59 is Zi hour 子时, linked with the Rat. Treat this as a cultural time-period lookup, not a complete chart calculation.
Zodiac hour vs birth-year zodiac sign
The hour animal does not replace your birth-year animal. Your year sign is the broad public-facing layer most people know. The hour sign is a time-of-day layer connected with the Earthly Branch used for that two-hour period.
The familiar Chinese zodiac sign based on your lunar birth year, such as Dragon, Horse, or Rabbit.
The animal linked with the two-hour period of your birth time, such as Zi Rat or Wu Horse.
A complete chart uses year, month, day, and hour pillars. This page only explains the hour branch layer.
To find your birth-year animal and element, start from the homepage calculator or use the Tableau des années du zodiaque chinois.
How zodiac hours connect with Earthly Branches
The real structure behind zodiac hours is the 12 Earthly Branches, or Branches terrestres dìzhī. The animals are the more familiar symbols attached to those branches.
This is why zodiac hours follow the same order as the animal cycle: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig. The hour layer is one way the branch-animal system appears in daily time.
The 12 branches label years, months, days, and hours in traditional time systems.
The animal names make the branch sequence easier to remember and explain.
The day is divided into 12 two-hour periods, each linked with a branch and animal.
Common mistakes
- Expecting the hour animal to replace the year animal. It does not. It is an additional time layer.
- Assuming midnight starts the first zodiac hour. Zi hour begins at 23:00 and crosses midnight.
- Thinking each zodiac hour is 60 minutes. A traditional zodiac hour is about two modern clock hours.
- Using this as a full BaZi calculator. A full chart needs year, month, day, and hour pillars, not birth time alone.
- Forgetting time zone and birthplace in serious chart work. This simple tool uses the clock time you enter.
- Reading the result as fixed personality science. Zodiac hours are cultural time labels, not scientific personality categories.
FAQ
What is my Chinese zodiac hour?
Your Chinese zodiac hour is the animal sign linked with the two-hour period in which you were born. For example, 23:00–00:59 is Zi hour 子时, linked with the Rat.
Is the Chinese zodiac hour the same as my zodiac sign?
No. Your usual zodiac sign comes from your birth year. The zodiac hour comes from your birth time. They are different time layers.
Why does Rat hour start at 11 p.m.?
In the traditional 12-hour system, Zi hour 子时 runs from 23:00 to 01:00. It crosses midnight, which is why late-night births can feel confusing.
What time is Horse Hour?
Horse Hour is Wu hour 午时, traditionally 11:00 a.m. to 12:59 p.m. It is linked with the Horse 马 and the Earthly Branch 午.
Does this calculator make a full BaZi chart?
No. It only maps a birth time to the traditional two-hour zodiac period. A full BaZi chart uses year, month, day, and hour pillars.
Should I use local time?
For this simple cultural reference, use the local clock time of birth if you know it. Formal chart work may require more precise time handling, including birthplace, time zone, and sometimes solar-time adjustment.
What if I only know an approximate birth time?
You can still use the result as a cultural reference, but be careful near the boundary between two zodiac hours. A time close to a boundary may change with a more exact birth time.
