How digits are reduced
The life number here uses only the birth date. Add the digits, then reduce. 11, 22, and 33 stay as master numbers and are not added further.

From a date to one number
Add every digit of the year, month, and day. If you still have two digits, add those, until one digit remains. If the running total is 11, 22, or 33, stop. Do not reduce them to 2, 4, or 6. Birth time and place never enter the arithmetic. Knowing the hour does not change the life number.
A master number is a rule, not a higher grade
Keeping 11, 22, and 33 separates them from an ordinary reduction. It does not make a higher kind of person, and it is not a guaranteed talent. If the tool does not compute a name number, the wiki does not invent a second alphabet. A life number is also not a BaZi day master.
One date, walked through
Illustration: the digits sum to 29, and 2+9=11. Eleven is a master number, so it stays 11 and is not reduced to 2. A sum of 38 also becomes 11 and stops. A sum of 19 becomes 10, then 1, because no master number appeared. This is arithmetic, not a rank of fate. The number also cannot choose a day for surgery or a contract.
Common mistakes
- Reducing 11 further to 2.
- Turning a master number into a guaranteed talent.
- Letting a birth time change the life number.

Frequently asked questions
Does the life number need a birth time?
No. Only the birth date. Hour and place belong to BaZi, Zi Wei, or astrology.
Can I read 11 and 2 as the same number?
The rule here keeps 11. Do not call it 2 because that is easier to explain.
Can a name produce a number too?
If the live tool does not compute a name number, it is not computed here. Do not supply an alphabet of your own.
