Grandma's
compatibility test.

Before DNA, there were star signs, gotras and an aunty with opinions. Put in your birthdays and find out what the stars think. Then find out what your DNA thinks.

Two birthdays is all grandma needs. Names and gotras make it juicier.

How grandma scores it.

Classic astrology pairs signs by element. Same element gets on best, then fire with air and earth with water.

FireAries, Leo, Sagittarius. Best with fire and air.
EarthTaurus, Virgo, Capricorn. Best with earth and water.
AirGemini, Libra, Aquarius. Best with air and fire.
WaterCancer, Scorpio, Pisces. Best with water and earth.

Kundli, gotra and the original compatibility tests

In much of South Asia, families still match horoscopes before a wedding. Kundli matching compares two birth charts across 36 points, and 18 or more is traditionally a pass. It needs exact birth times and places, so it's normally done by an astrologer, not a quick web form.

Gotra is different, and actually about family. It's a lineage passed down the father's line, and marrying within your gotra is avoided because it implies a shared paternal ancestor. The catch: it says nothing about your mother's side, adoptions or anyone whose records got lost.

Orthodox Jewish communities took it further. Since 1983, Dor Yeshorim has screened young people for recessive conditions and told couples one thing: compatible or not. That's a carrier check, decades before it was cool.

We think grandma was onto something. She just didn't have DNA.

The stars said yes. Ask your DNA.

Check if you're related, then check if you carry the same hidden condition. Private, consent-first, from home.

Compatibility questions.

Which zodiac signs are most compatible?

In traditional astrology, signs of the same element (fire, earth, air or water) get along best, followed by complementary pairs: fire with air and earth with water. It's fun, not science.

What is kundli matching?

Kundli matching (Guna Milan) is the Hindu tradition of comparing two birth charts before marriage. It scores 36 gunas, and 18 or more is traditionally considered acceptable. It needs exact birth times and places, which is why it's usually done by an astrologer.

What is a gotra and why does it matter for marriage?

A gotra is a Hindu lineage traced through the father's line. Many families avoid marriages within the same gotra because it signals a shared paternal ancestor. It doesn't track the mother's side at all, which is where DNA comes in.

Can astrology tell if we're related?

No. Neither can a love calculator. The only way to know if you share ancestry is to compare DNA. The only way to know if you carry the same hidden condition is a carrier screen.
