What is mulank (birth number)?
Your mulank (mulank ka arth: 'root number') is the birth number derived from the day of the month you were born, reduced to a single digit 1–9. Born on the 23rd? 2 + 3 = 5, so your mulank is 5. It is the 'everyday self' in Indian (Chaldean) numerology — the vibration you lead with — and each mulank answers to a ruling planet.
The calculator takes your date of birth and returns your mulank and its ruling planet instantly. Note the mulank uses only the day; your bhagyank (destiny number) uses the full date, and the two together give the fuller picture.

Frequently asked questions
How do I calculate my mulank?
Add the digits of your day of birth and reduce to one digit. Born on the 27th: 2 + 7 = 9, mulank 9. The calculator above does this from your date and also names the ruling planet.
What is the meaning of mulank (mulank ka arth)?
Mulank means 'root number' — your birth number from the day of the month, reduced to 1–9. It represents your core, everyday nature in numerology, ruled by one of the nine planets.
Which mulank is ruled by which planet?
1–Sun, 2–Moon, 3–Jupiter, 4–Rahu, 5–Mercury, 6–Venus, 7–Ketu, 8–Saturn, 9–Mars, in the Chaldean system used in India. For example, mulank 3 and mulank 5 are ruled by Jupiter and Mercury respectively; the number ruled by Jupiter is 3.
What is the difference between mulank and bhagyank?
Mulank comes from the day of birth alone (your everyday self); bhagyank comes from the entire date of birth (your life direction). A complete reading weighs both, plus your name number. Use our bhagyank calculator for the second.
Is any mulank lucky or unlucky?
None is unlucky. Each carries strengths and lessons through its ruling planet. 'Luck' in numerology is about aligning your name number and choices with your mulank and bhagyank — not about the birth number being good or bad in itself.
