Lucky Number Calculatorभाग्यांक
Reviewed by Pt. Deep Narayan Mishra, Consulting Astrologer · Last reviewed 24 May 2026 · How we compute this
Your Mulank — the lucky number derived from your date of birth — together with the lucky colour, weekday, direction and gemstone traditionally assigned to its ruling planet. Computed instantly in your browser using the classical Indian numerology (Cheiro / Sethi) and Vedic ratna-shastra correspondences.
How this is computed
- Mulank is the digit-sum of the day of birth (e.g. 15 -> 1 + 5 = 6).
- Bhagyank is the digit-sum of the full date of birth (day, month, year), reduced to a single digit.
- Each Mulank has a ruling planet (1 Sun, 2 Moon, 3 Jupiter, 4 Rahu, 5 Mercury, 6 Venus, 7 Ketu, 8 Saturn, 9 Mars). The lucky colour, weekday, direction and gemstone are the classical correspondences carried by that planet — from the Cheiro and Vedic ratna-shastra traditions.
- These are traditional associations, not deterministic forecasts. Use them as preferences, not predictions.
How to use it
- Enter your date of birth: Pick your date of birth in the date input. Only the day matters for the lucky number, but the full date is used for your Bhagyank (destiny number).
- Read your lucky number and attributions: The tool shows your Mulank (lucky number), ruling planet, lucky colour, weekday, direction and primary gemstone, plus your Bhagyank.
- Use them as preferences, not predictions: Treat the colours, day and direction as favourable traditional choices for clothing, travel, decor and start-of-work timing — not as a forecast of luck.
Frequently asked
What is a lucky number in Indian numerology?
Your lucky number is your Mulank — the single digit (1 to 9) obtained by reducing the date of the month you were born. Each Mulank is governed by a classical planet, and the colours, weekday, direction and gemstone traditionally associated with that planet are considered favourable for the person.
How is the Mulank (lucky number) calculated from a date of birth?
Take only the date of the month you were born and add its digits until a single digit remains. For 15, Mulank is 1 + 5 = 6. For 29, Mulank is 2 + 9 = 11 then 1 + 1 = 2. The month and year are not used for the Mulank — they are used for the Bhagyank (destiny number), which this tool also returns.
What is the difference between Mulank and Bhagyank?
Mulank is your psychic / root number from the day of birth alone. Bhagyank is your destiny / life-path number from the full date of birth (day, month, year). The classical view is that Mulank shows immediate temperament while Bhagyank shows longer-term life direction. Both are read together.
Where do the lucky colour, day, direction and gemstone come from?
Each Mulank has a ruling planet (1 Sun, 2 Moon, 3 Jupiter, 4 Rahu, 5 Mercury, 6 Venus, 7 Ketu, 8 Saturn, 9 Mars). The lucky colour, weekday, direction and primary gemstone are the classical correspondences carried by that planet — for example, Sun -> Sunday, gold / orange, East, Ruby. The planet -> direction map follows the standard Vedic dig-bala assignments.
Why do Rahu and Ketu show 'Any' as the lucky day?
Rahu and Ketu are the shadow nodes and are not assigned a single weekday in the classical seven-day planetary scheme. Rather than fabricate a day, we surface 'Any' so the result stays faithful to the source tradition. Ketu similarly has no fixed cardinal direction in classical references, so its direction is also shown as 'Any'.
Is the lucky number really a prediction of luck?
No. These are traditional associations carried in Indian numerology (Cheiro / Sethi tradition) and Vedic ratna-shastra — they describe affinities the tradition assigns to your number, not a deterministic forecast. We surface them so you can use them as preferences, not as prophecy.
Should I wear the gemstone the tool suggests?
Gemstones in classical ratna-shastra are powerful and are not meant to be self-prescribed from a calculator. The gemstone shown here is the standard one for your Mulank's ruling planet, but a full chart consultation with an experienced astrologer is the right way to decide whether — and how — to wear it.
Can two siblings have the same lucky number?
Yes. The Mulank depends only on the day of the month, so any two people born on the same date — siblings, friends, strangers — share the same lucky number, colours, day and direction. Their Bhagyank and full birth chart will still differ.
