General Rule (2)

In traditional Chinese age counting, a new born baby is one year old. And everybody's age gets incremented by one on Chinese New Year. So a baby born a day before Chinese New Year could be two years old a couple of days after birth. This rule is very important because errors always occur on miscalculating the age of mothers.

To avoid confusions and errors, we have set up four easy steps which help you find the correct mother's age on conception.

Step 1. - Subtract the mother's 'birth year' from the 'conception year', get the result.
Step 2. - Find out if the mother's birth date was before or after the lunar new year in that year?
Step 3. - Find out if the conception date is before or after the lunar new year in that year?
Step 4. - Check the following table and add the 'additional age' to the result of step 1.

Table for additional age

Time of Conception	Birth Date
	Before lunar new year	After lunar new year
Before lunar new year	Area A (+1)	Area B (+0)
After lunar new year	Area C (+2)	Area D (+1)

Example 1. What was the lunar age of a girl on Jan. 4, 2003 if she was born on Feb.2, 1962 ?

2003 Gregorian-Lunar Calendar

Answer : 42

Step 1.	2003 - 1962 = 41
Step 2.	Look at the 1962 Gregorian-Lunar Conversion Table , Feb. 2 was a date before the lunar new year (on Feb. 5, 1962)
Step 3.	Look at the 2003 Gregorian-Lunar Conversion Table , Jan. 4 was a date before the lunar new year (on Feb. 1, 2003)
Step 4.	Check for the additional age table, and we find that one more year (Area A) has to be added to the result of step 1. So, 41 + 1 = 42

Example 2. What was the age of a girl on Feb. 6, 2003 if she was born on Feb.2, 1962 ?

2003 Gregorian-Lunar Calendar

Answer : 43

Step 1.	2003 - 1962 = 41
Step 2.	Look at the 1962 Gregorian-Lunar Conversion Table , Feb. 2 was a date before the lunar new year (on Feb. 5, 1962)
Step 3.	Look at the 2003 Gregorian-Lunar Conversion Table , Feb. 6 was a date after the lunar new year (on Feb. 1, 2003)
Step 4.	Check for the additional age table, and we find that two more years (Area C) have to be added to the result of step 1. So, 41 + 2 = 43
