Can you do kundli matching without a birth time?
Not reliably, and our Kundli matching tool asks for a birth time for both people. Without one, the Moon-based points stay the same only if the Moon was in one sign and one nakshatra the whole day, which often is not the case. The rising sign and the houses, including the Lagna-based Manglik check, cannot be worked out at all.

Why the time matters
Every koota depends on the Moon. The Moon moves roughly 12 to 15 degrees a day, and a nakshatra is 13 degrees 20 minutes wide, so the Moon takes about a day to cross one nakshatra and on most days moves into the next one at some hour. It changes sign every two to two and a half days. A pada, a quarter of a nakshatra, lasts only about six hours.
What can still be said without a time
Four kootas use only the two Moon signs: Varna, Vashya, Graha Maitri and Bhakoot, 15 points in all. If the Moon stayed in one sign for the whole birth date, these are the same at any hour.
The other four, Tara, Yoni, Gana and Nadi, 21 points in all, use the nakshatra. They are fixed only if the Moon stayed in one nakshatra all day. On a day when the Moon changes sign or nakshatra, a matching result without the time can simply be wrong.
To see whether this applies to a birth date, enter that date in the nakshatra calculator twice, once with a time just after midnight and once just before the next midnight. If both show the same nakshatra, the Moon-based points will not change with the time, although the pada may.
What cannot be worked out
- The rising sign (lagna), which changes about every two hours.
- The twelve houses, which are counted from the lagna.
- The Manglik check counted from the lagna. The counts from the Moon and Venus are often possible, but most families mean the full check.
- The pada of the nakshatra, which some Nadi cancellation rules need.
- A full chart review, which an astrologer would base on the houses and much more.
A guessed time is an estimate
Some sites quietly use noon or midnight when no time is given. The result then looks exact but is an estimate: if the Moon changed nakshatra that day, the guessed time may pick the wrong one and change several kootas. If you use a guessed time anywhere, treat the score as approximate and say so when you share it.
Where to find a birth time
Some astrologers offer birth time rectification, which estimates a time from life events. It is an interpretation, not a record, so treat its result as an estimate too.
- The birth certificate, which in many places records the time.
- The hospital or nursing home record of the birth.
- Parents, grandparents and other elders who were there.
- A janam patri or horoscope made by the family soon after the birth.
Frequently asked questions
Can kundli matching be done without birth time?
Only roughly. The Moon-sign points are reliable if the Moon stayed in one sign all day, and the nakshatra points if it stayed in one nakshatra. The lagna, houses and the Lagna-based Manglik check need the time.
Which time should I use if I don't know my birth time?
Any guessed time, such as noon, gives an estimate, not a result. Check whether the Moon changed nakshatra that day; if it did, the guess can change the score.
Is kundli matching by name accurate?
No. Matching by name guesses a nakshatra from the first sound of the name, which is often different from the real birth nakshatra.
What if only one person knows their birth time?
The same limits apply to the person without a time, so the result is only as reliable as that person's Moon position for the day.
How can I find my exact birth time?
Look at the birth certificate and the hospital record, and ask parents or elders. A horoscope made by the family soon after the birth often notes the time.
