This marriage prediction calculator turns two birth dates into a score out of 100. It publishes its full formula, shows every part of the calculation next to the result, and the same two dates always give the same score. Nothing is stored or sent anywhere — the arithmetic runs entirely in your browser.
Type the day, month and year as a full date. The calculator uses the ISO date format to turn it into a life path number.
Add the other person’s date of birth. The two fields are independent, so the dates can be from any year.
The marriage score appears instantly, along with the two life path numbers used and the exact arithmetic behind the result.
Each factor is listed separately — base group, same-number adjustment, divisibility by nine, and any difference of four or five.
Every marriage score on this page comes from a fixed, published calculation, and the result screen shows each part of it. The first step is turning each birth date into a life path number. The digits of the ISO date are added, and the total is reduced to a single digit from 1 to 9.
For example, 15 August 1990 gives 1+5+0+8+1+9+9+0 = 33, and 3+3 = 6. Once both life path numbers exist, they are put through a pair matrix. The numbers fall into three groups: independent is 1, 5 and 7; grounded is 2, 4 and 8; expressive is 3, 6 and 9.
A pair from the same group starts with a base score of 88. Independent plus expressive starts at 72. Grounded plus expressive starts at 64.
Independent plus grounded starts at 48. After the base score, three modifiers can apply. If the two life path numbers are the same, the score drops by 6.
If their sum is divisible by 9, it rises by 10. If the difference between the numbers is exactly 4 or 5, it drops by 10. Finally, the result is clamped between 0 and 100.
There is no hidden term, no random value, and no interpretation of the dates beyond this arithmetic.
Kundli matching is a traditional method that examines birth charts across many factors. This calculator does none of that. It reduces two dates to life path numbers and applies a fixed matrix.
It cannot detect doshas, gunas or planetary positions, and it does not attempt to. If you have a kundli, this score may or may not agree with it; the two methods answer different questions. Use this page as a quick, repeatable number based only on the dates you type.
No. A date of birth cannot predict whether a marriage will happen or last, because human relationships do not run on arithmetic. This calculator turns two dates into a repeatable score out of 100 using a published formula, and nothing else. Think of it as a game with transparent rules — it can tell you the score for the dates you enter, but it cannot see the people behind them.
This page is built for one question: a marriage score from two birth dates. Birthday compatibility usually asks how two people get along in general, and may weigh many traits. Here the formula is narrower — two life path numbers, a base matrix, three modifiers and a clamp. The score is stated as a marriage prediction number, but it is still just arithmetic on dates.
No. Kundli matching compares detailed birth charts, including positions at the time and place of birth. This calculator only sees the digits in two dates, so it cannot detect doshas, gunas, or planetary placements. If you have a kundli, treat the result here as a separate, much simpler number. It does not confirm or contradict an astrologer's reading.
Because the calculation has no random part and no reference to today's date, your location, or anything else. The formula is fixed: sum the ISO date digits, reduce to a life path number, match the pair through the matrix, apply the three modifiers and clamp. Run that with the same two dates tomorrow or in five years, and the output will be identical.
No. The two birth dates are never sent to a server, because the calculation runs entirely inside your browser. There is no sign-up, no account, and no database to write to. Once you close the tab, nothing you typed is kept on your device or anywhere else. The score exists only while you look at it.
In this tool, the life path number is simply the sum of all digits in a birth date, reduced to a single digit from 1 to 9. It is not a personality profile or a destiny reading. It exists only to place the date into one of three groups — independent, grounded or expressive — so the pair can be matched by the base matrix.
