According to a Chinese Astrology interpretation, the twelve Chinese signs are associated with years, seasons and months.

Here are the twelve animals, their favorable month and the associated season of the year:

Rat: Winter | December
Ox: Winter | January
Tiger: Winter | February
Rabbit: Spring | March
Dragon: Spring | April
Snake: Spring | May
Horse: Summer | June
Sheep: Summer | July
Monkey: Summer | August
Rooster: Autumn | September
Dog: Autumn | October
Pig: Autumn | November

Animals are very active during their favorable month and season. All their attributes and characteristics are far more obvious and bold during their associated month. Chinese signs rule over days of the week too:

Rat: Thursday
Ox: Saturday
Tiger: Saturday
Rabbit: Friday
Dragon: Tuesday
Snake: Friday
Horse: Wednesday
Sheep: Monday
Monkey: Sunday
Rooster: Saturday
Dog: Friday
Pig: Thursday

So the twelve Chinese Horoscope signs rule over years, seasons, months, days. They also rule over hours of the day. I will present  hour categorization in another post. When an animal rules over a year it is more powerful than when it rules over a season or month. When an animal rules over a month or season it is more powerful than when it rules over a

day. Let's see how this works:

Let's say its Monday. July 28, 2008
Let's find the rulers for this day..

Year 2008 is ruled by the Rat.
It is Summer and the rulers for this season are the Horse, the Sheep and the Monkey.
It is July so the ruler for this month is the Sheep.
It is Monday and the ruler for this day is the Sheep.

So this day (28/7/2008) is ruled by:

- The Rat which is the most powerful ruler since it rules over the year.
- The Sheep which follows as a ruler of the month and the specific date.
- The Horse and the Monkey which are less powerful during that date, since they are season rulers.

You can find more information about each Chinese sign in my free website about Chinese Astrology and Chinese Horoscope:

is really the first time i know that the chinese 12 signs can represent day. TQ Duan, is sound interesting.

Thanks for this info, but your example is very simple, because Monday rule only one animal, Sheep. My question is how could you pick up animal for example some Saturday, because as I see in your post it may be Tiger, Rooster or Ox?  

Also, do you know some site where I can find explanation about predicting winner of some sport contest by chinese astrology. What do you think it is more important to look in that case (I am a big sport fan), for particular day and time?? Do you have some example?

It seems as though you are referring to some information in the Stem Branch system used to determine things such as Day / You, Month, Year
And the time of birth to determine hour.

Each when using it based on a particular person will also help understand parent, ancestor, you, child relationships.

There were some animals that you show referring to more  than one day, how do you determine which is which?
One site that does discuss this branch stem system, has put the date you use as this:

Day (you)             Month              Year
Female Soil          Female Soil      Male Soil
Brown Snake       Brown Sheep    Brown Rat

Could you share your reference sources so I could read up and learn more?

thanks dessa

This site listed looks interesting, though a bit hard to follow not sure where from it you got the listing of seaons, days etc, or was it from another source?
