The year and month use for constructing a 4 Pillar chart must base on the 24 Solar Terms.
For a birth year, a year offically start on the day of “Start of Spring”. This means 2009 the year of the Ox, the Start of Spring is at 0050 on the 4th February 2009. So anyone was born after 0050 on the 4th February 2009, this person carries an animal sign of Ox. For anyone was born before 0050 on the 4th February 2009, even thought the Chinese new year was on 26th January 2009, nine days before, this person carries an animal sign of RAT, not OX. (This bit is important)

Ok, let’s start construct a Four Pillars Natal Chart manually now.
In order to construct a four pillars natal chart, we need the birth data of a person and the gender of this person.
We need a Chinese Alamance. In Chinese it is called “Ten Thousand Years Calendar”. It has all the information need to build a Four Pillars chart. The information includes the year in Heavenly Stem and Earthly Branch that is the Year Pillar. The particular month in Heavenly Stem and Earthly Branch that is the Month Pillar. The date in Heavenly Stem and Earthly Branch that is the Day Pillar. In Four Pillars of Destiny's jargons, the Day Pillar also called the Day Master or DM.
There is also information about the 24 Solar Terms in the “Ten Thousand Years Calendar” too.
The Hour Pillar is not included in the “Ten Thousand Years Calendar”. At the beginning, you need a table to find out the Heavenly Stem for the hour. However, there is a way to store the hourly Heavenly Stem into the palm (the body part palm not the palm pc). Once you have learnt it you will never forget. You may forget to bring the hourly Heavenly Stem table with you, but you will never forget to bring your own palm.
Have you ever seen a Feng Shui Master using the thumb pointing over the four fingers? After the moving around the thumb, the Bazi Master can tell you the Heavenly Stem for the hour. Or sometimes, the Bazi Master can tell you what is going to happen. Well, it is hard to teach you now. I will draw a table for you instead.
Here is a part of a page of the “Ten Thousand Years Calendar” in 1965.

The birth data, western calendar, 10pm 11th August, 1965. I underlined the year, month and day pillars in red.
After checking at the “Ten Thousand Years Calendar” we have the following 4 pillars.
How does the Hour pillar –Metal pig come from? Just look at the following table.

The person was born on the Ding day at 10pm, so just look at the Ding day in the fifth column and go down to the 21-23 Pig's intersection. The Heavenly Stem is Xin. So the hour pillar is -Xin Pig.
