Solar Term - Spring Begins February 4th, 2011




 立春
Spring Begins
Solar Term Number One of Twenty Four

In the Chinese Solar Calendar, the first day of the year is marked by the Solar Term, "Spring Begins" or "Li Chun" (Han yu pin yin). It usually falls on 4th, 5th, or 6th of February. In 2011, Li Chun is on 4th of February. 

There is a little bit of non-uniformity of the use of this word as the geography of China covers a vast area. In Mongolia towards the north of China, it is still blistering cold with snow. Technically, according to baidu.com, the area around 黄河, Huang He, The Yellow River and down south is the reference zone for recording this Solar Term. The three pentads (each pentad = 5 days) poem is as follows for this month:

“一候东风解冻,
二候蜇虫始振,
三候鱼陟负冰”

In the first pentad, the easterly winds starts to melt the ice
In the second pentad, the ground beetles have started to move
In the third pentad, the fishes starts to move below the frozen waters

The Chinese language is wonderfully beautiful, and uses a lot of imagery to describe the meanings. As you can tell from the verse above, during this time, the earth is slowly coming to life from the frozen months of winter. 

In China, the temperature of between 10 - 22 degrees Celsius is the range for Spring.


Four Seasons

There is no better way to understand the 5 elements / processes than to experience the 4 seasons in a year. In tropical climates like Singapore, Indonesia and Malaysia, it is not possible to experience the four season. Do take more trips overseas to experience the seasons if you are a Feng Shui geek like me. Beyond "studying" what the 5 elements/processes are!

Using the 4 types of blossoms and plants in Chinese paintings to denote the 4 seasons is common. They are: Peach Blossom (Spring), Orchid (Summer), Chrysanthemum (Autumn) and Bamboo (Winter). 梅兰竹菊。 If you play mahjong, you will notice that these are the 4 flower tiles.



24 Solar Terms

By observing the path of the sun's shadow using a Gnomon stick, the ancient Chinese were able to design a Chinese calendar that was consistent and marked out the seasons accurately. The period of one year was divided into 24 Solar Terms, with 4 "establishment" markers to mark the beginning of each season. It helps to supplement the Lunar calendar that is based on the moon's cycle. 





3 months are assigned to each season, and the following 24 Solar Terms are created. The first pair of Chinese characters mark the beginning of the month, while the second pair of Chinese characters in the same line marks the half-way point of a month.


Calculation of Spring Begins

Formula : [Y*D+C]-L

Y = last 2 digits of the year
D = 0.2422
For the 21st century, C value = 3.87
For the 22d century C value = 4.15.
L is number of leap years 

For example: in 2058 the date of the calculation of the beginning of spring

[58 × 0.2422 +3.87] - [(58-1) / 4] = 
17-14 = 3, 
 and so Feb. 3 beginning of spring.

First Day of the Year

According to baidu.com, the historical records have shown that Li Chun day or Spring Begins was the day that was used for the first day of the year. The records also revealed that some even used the Winter Solstice day as the beginning of the New Year.

In the year 1912, Sun Yat Sen announced the use of the western gregorian calendar. In the year 1914, Yuan Shi Kai laid down the change that the Lunar Calendar be used for Chinese New Year, i.e. first day of the first lunar month. This has resulted in modern day confusion for those born in January or February as to which annual horoscope sign one belongs to.

The answer is simple :  the Chinese Tian Gan Di Zi (Heavenly Stems and Earthly Branch) system has always been used in the Solar Calendar and so the Li Chun day should be used for the year crossover date.
