Love Calculator by Name & DOB

How it works

Enter both names and both birthdays. All four are required here. The calculator strips each name down to letters only, sorts the pair, and runs it through a fixed formula to get a name-based score out of 100. It runs the two birthdates through a separate formula to get a date-based score, then blends the two: 60% names, 40% birthdays, rounded to the nearest whole number.

Each half is deterministic on its own, so the blend is too. The same two names and the same two birthdays always land on the same final number, no matter what order you type them in or how many times you check. Nothing is randomized and nothing gets looked up externally. The four values you enter are the whole calculation.

Everything happens in your browser. Nothing you type is sent to a server or saved anywhere. Only have names to work with, no birthdays? The plain Love Calculator skips the birthday step entirely. Prefer birthdays to stay optional instead of required? Try the Compatibility Calculator. Want to skip names altogether? The Birthday Compatibility Calculator works from two dates of birth alone.

Why blend names and birthdays at all

Name-only love calculators are the older, more familiar tradition, but folk compatibility systems have mixed names with birth dates for just as long. Numerology reduces every letter of a name to a number the same way it reduces a birthdate to a life path number. Astrology has always paired a sun sign, which comes entirely from a birth date, with a read on someone's personality tied to their name. Putting both into one calculator isn't a new idea. It's two existing folk traditions running side by side instead of separately.

The 60/40 split favors names on purpose. Names are the bigger half of the classic love-calculator format this tool comes from, so keeping them the larger share of the score keeps the result feeling like that original idea, while birthdays still carry enough weight to move the outcome.

Reading your combined score honestly

Blending two inputs can make a score feel more precise than a single one, but it isn't. Stacking a second fixed formula onto the first doesn't add real information about two people. It just changes the number that comes out the other end. Treat it exactly like the classic Love Calculator: something fun to share, not a verdict on a relationship you already know far more about than any formula does.

When your two reads don't agree

The result card shows more than the final number. Underneath it sits the breakdown: a name-based score and a birthday-based score, listed separately before they're blended into the final percentage. Sometimes the two land close together. Often they don't, and it's worth knowing why before reading too much into either one.

Because names and birthdays run through two completely separate formulas, there's no reason for them to naturally agree. A high name score paired with a low birthday score, or the reverse, doesn't mean anything is being measured incorrectly. It means two unrelated fixed calculations happened to land on different numbers for these two specific inputs, the same way two different dice rolls don't need to match.

If you're curious which half is driving your final score, the 60/40 weighting means the name-based number moves the outcome more. A dramatic swing in the birthday score alone will shift the final percentage less than an equally dramatic swing in the names. That's by design, not a flaw in the birthday half of the formula.
