Enter both partners’ dates of birth and a month above, and this free calculator reads every day of that month the way our favourable dates by moolank tool does, once for each of you. It then lists the days that read supportive for both partners, and shows the working for a date you have in mind. It is a numerology reading, and for a Hindu wedding the day is traditionally chosen by the panchang muhurat, which the vivah muhurat for a couple tool finds.
How it works
Each partner’s moolank is the day of birth reduced to one digit, as the moolank and bhagyank page explains. Each day of the month then gives three numbers: the day number (the day of the month reduced), the date number (every digit of the day, month and year added and reduced) and the number of the planet that rules the weekday. Sunday is the Sun (1), Monday the Moon (2), Tuesday Mars (9), Wednesday Mercury (5), Thursday Jupiter (3), Friday Venus (6) and Saturday Saturn (8).
Each of the three numbers is read against a partner’s moolank with the friendly, neutral and less comfortable lists printed on the number pages, which follow the natural friendships of the planets in Brihat Parashara Hora Shastra (chapter 3, verse 55, Santhanam’s edition), with Rahu (4) and Ketu (7) placed by a common numerology convention. A reading scores 3 for the same number, 2 for friendly, 1 for neutral and 0 for less comfortable, so each partner gets a figure out of 9. A day is supportive at 5 or more and most supportive at 7 or more, the same bands as the favourable dates tool.
Here is a worked example. For 12 December 2026, a Saturday, the day number is 1 plus 2, which is 3. The digits 1, 2, 1, 2, 2, 0, 2 and 6 add up to 16, and 1 plus 6 is 7, so the date number is 7. Saturday’s lord is Saturn, 8. For a partner with moolank 3, the 3 is the same number, 7 is friendly and 8 is neutral, which is 6 of 9 and supportive. For a partner with moolank 6, the 3 and the 7 are neutral and the 8 is friendly, which is 4 of 9 and mixed. The tool would call that day supportive for one of you.
Reading the result
The headline gives the number of days in the month that read supportive for both partners, and how many of them read most supportive for both. Two lists follow, then a table of every day with both scores and a line for the two of you: most supportive for both, supportive for both, supportive for one of you, or mixed or less supportive for both. Days that read well for both are not common, because they need the day, the date and the weekday to agree with two moolanks at once. In our check of 169 months for a range of couples, 948 of 5,044 days read supportive or most supportive for both, and 71 most supportive for both.
If you choose a date you have in mind, the headline reads that date, and a small table shows how each partner’s moolank and bhagyank list its three numbers. Only the moolank columns are counted in the score, as on the favourable dates tool. The bhagyank columns are there for interest.
Where traditions differ
Numerology teachers differ on which number of the couple to use. Some read the moolank, some the bhagyank, some a name number, and Western numerology keeps master numbers such as 11 and 22, which the Indian method reduces. This tool follows our favourable dates tool and scores the moolank, and shows the bhagyank beside it. The score out of 9 is our way of summarising the lists and not a classical score.
The panchang tradition chooses a wedding day in a different way altogether: the Vivaha prakarana of the Muhurta Chintamani looks at the Moon’s nakshatra, the Sun’s month, the tithi and the weekday, as the vivah muhurat guide explains, and the couple tool also checks both partners’ Moons. Where the two disagree, families who follow the panchang give the muhurat the final word.
What it does not do
It does not say whether a marriage will be happy, and no date can promise that. It does not replace the vivah muhurat, the kundli matching or the family priest’s advice, and it does not look at the tithi, nakshatra or any planet in the sky on the day. A day that reads less supportive here is not a bad day for a wedding. Numerology is a traditional practice for reflection and not a science.
Frequently asked questions
↳ How do you calculate wedding date numerology?
Take three numbers from the date: the day of the month reduced to one digit, every digit of the full date added and reduced, and the number of the weekday's planet. Read each against each partner's moolank with the friendly, neutral and less comfortable lists, and score them 3, 2, 1 or 0. The tool does this for every day of the month and shows the working.
↳ Which wedding date number is lucky?
No number is lucky in itself. The tradition lists numbers that are friendly to your moolank and numbers that are less comfortable, so a date that suits one couple may not suit another. The tool reads each date against both of you.
↳ Do the bride's numbers count more than the groom's?
This tool gives both partners the same weight and shows each partner's score separately, so you can see where the two differ. A day that reads supportive for both is listed first.
↳ Does this replace the vivah muhurat?
No. For a Hindu wedding the day is traditionally chosen from the panchang. Use the vivah muhurat for a couple tool to find the classical days, and read this numerology as a light second view if you like.
↳ What if no day in the month reads supportive for both of us?
That is common, and it means only that the lists give fewer matches that month. Look at the days that suit one of you, try another month, or let the muhurat decide. A less supportive reading is not a warning.
↳ Can I check the date of a wedding that has already happened?
Yes. Choose the month and year, from 1900 onwards, and the date in the box for the date you have in mind. The reading is the same for a past date as for a future one.
↳ Does the tool keep our dates of birth?
It works in your browser. Once your email is confirmed, what you enter and the headline of the result are kept with your email, so our emails can fit you. You can delete them at any time; the privacy policy has the detail.
