Numerology calculator: mulank, bhagyank and name number

The numerology calculator from API for Astrology (apiforastrology.com) finds three core numbers from a name and a birth date. You get the mulank (driver number) from the birth day and the bhagyank (conductor number) from the whole date. You also get the name number in the Chaldean letter system, the one Indian numerology uses most.

The mulank is also called the birth day number, and the bhagyank the destiny number. We do not store the details you enter.

How the numerology calculator works

The mulank is the day of birth, with its digits added until one digit is left. Born on the 15th, you get 1 + 5 = 6. The bhagyank adds every digit of the full date in the same way. When the bhagyank or name total passes through 11, 22 or 33, the API flags a master number. The Indian numbers still end on one digit.

The name number gives each letter a value and adds them up. The tool reads it in the Chaldean system, the one Indian numerology uses most. In it, no letter is worth 9. The Pythagorean number, used in Western numerology, is shown beside it but not read. Names must be in English letters, because each spelling gives a different number.

The same POST /v1/profile request, with your own API key, returns all of this as JSON. It also returns the lucky day, colors, friendly numbers and the Lo Shu grid.

Worked example: John Doe's numbers

John Doe was born on August 15, 1990. His birth day is the 15th, and 1 + 5 = 6, so his mulank is 6. The digits of his full date add up to 33, and 3 + 3 = 6. So his bhagyank is also 6, and the API flags 33 as a master number on the way.

His name adds up to 34 in the Chaldean system, and 3 + 4 = 7. So his name number is 7.

Method and sources

Every number here comes from simple counting on the name and date you enter. So the same details always give the same result. The letter values and the counting rules are on the numerology conventions page.

The mulank (birth day number) is the day of birth, added down to one digit. The 1st, 10th, 19th and 28th all give 1, as in Cheiro's Book of Numbers (1926). The Chaldean letter values, with no letter worth 9, follow the table in Cheiro's Book of Numbers (1926).

Common questions

All questions
How is the mulank different from the bhagyank?

The mulank uses only the birth day, from the 1st to the 31st. Everyone born on the 6th, 15th or 24th has mulank 6. The bhagyank uses the whole date, so it changes with the month and year. Indian numerology reads the mulank for everyday nature. It reads the bhagyank for the path life tends to take over time.

What the mulank is
Why Chaldean and not Pythagorean?

Chaldean is the letter system Indian numerology uses most, so the tool reads it by default. Pythagorean gives the letters 1 to 9 in alphabet order, and it is common in Western books and apps. The tool shows both numbers, labelled, and reads only the Chaldean one.

Compare both systems
Can I enter a name in Hindi?

No. Names must be written in English letters (A to Z). A name in another script is refused, not converted, because each English spelling gives a different number. Enter the spelling the person actually uses.

How names are read
What does a master number mean in the numerology calculator?

Some totals pass through 11, 22 or 33 on the way to one digit. The API flags these as master numbers. Of all birth dates from 1926 to 2025, about one in six gets the flag for its bhagyank. John Doe's birth date adds up to 33, so his bhagyank is 6 with the master flag set. The Indian numbers keep the single digit. The Western numbers, such as the life path, keep the master number itself.

Try the life path calculator
Can I add the numerology calculator to my own app?

Yes. Sent with your own API key, POST /v1/profile returns all three numbers as JSON, each with a short reading. It also returns the lucky day, colors, friendly numbers, remedies and the Lo Shu grid. One live call uses 3 reading credits.
