Don't know your birth time? You can still get a kundli — just not a complete one

This is the most common situation in India. The family remembers the date, but nobody is sure about the time. The real question isn't whether a kundli can be made — it can. The question is which parts of it you can trust and which you can't. That is written out plainly below, with nothing hidden.

✦ Want to go straight to the tool? Open Free Kundli and tick “I don't know the birth time”. The time field switches off, and you will be shown only what can genuinely be worked out without it.

First, understand what the time actually changes

The lagna (ascendant) is the sign that was rising on the eastern horizon at the moment you were born. It does not sit still — it shifts by roughly one degree every 4 minutes, and moves through a whole sign in about two hours.

And the lagna is the first house. The other eleven are counted from it. Which means guessing the time is not just guessing one number — it shifts the entire frame of the chart. Which house you read for career, which one for marriage: all of it moves.

So it is wrong to say “no kundli without a time”, and equally wrong to say “it makes no difference”. The truth sits in between.

Without a time: what holds, what doesn't

Planet's signUsually unchanged. Mars, Mercury, Jupiter, Venus and Saturn don't move far enough in a day to change sign — only if they were already near a boundary.

Moon's signSometimes changes. The Moon covers about 13 degrees in a day, so near a boundary two signs are possible.

Moon's nakshatraCan be one of two. A nakshatra spans 13°20′ — roughly the distance the Moon travels in a single day.

LagnaNot reliable. All twelve ascendants pass in one day.

The 12 housesNot reliable — they are counted from the lagna.

Vimshottari dashaReliable only if the nakshatra is certain. The dasha's starting point is set by the Moon's nakshatra.

A common practice that isn't right

Many free kundli tools quietly assume midnight when no time is given, and then draw the full chart anyway — lagna, houses and all.

On screen everything looks equally trustworthy. But that lagna is not yours — it belongs to an assumed midnight. Sometimes the assumption is disclosed, but in a hover note so small that it never appears on a phone — and a phone is where most people are. Either way the result is the same: a guess enters the chart, and travels into every sentence you read afterwards.

To our mind this is the worst mistake available here: not knowing, and presenting it as knowing.

What we do instead — the three-moment method

When you tick “I don't know the birth time”, we don't quietly settle on one. A full chart is calculated at three moments of that day:

00:01 — the very start of the day
12:00 — midday
23:59 — the end of the day

The three are then compared, and the result follows these rules:

Anything identical across all three is shown as settled.
Anything that changes is shown with all its options — not hidden. You will see plainly that “the Moon is either in this sign or that one”.
Lagna and the 12 houses are not shown at all. Leaving them out is deliberate: displaying something that cannot be derived is a lie.
The dasha appears only when all three moments give the same Moon nakshatra. If two are possible, the dasha is withheld.

None of this is estimated — it is recalculated each time, for your own date and place.

✦ Try it: make a free kundli — you only need the date of birth and the city. There is a tick box for leaving the time blank.

Where to look for the actual time

If half an hour of searching turns up the real time, that beats the three-moment method every time. The usual places it is written down:

Birth certificate — from the municipality or panchayat. Several states record the time on it.
Hospital discharge card or labour-room record, if the family kept it.
An old janmpatri — if one was cast at the time of birth, the time is written inside it.
Family memory — “at the time of the azaan”, “before the milk arrived”, “at evening aarti”. This won't give an exact time, but it does give a two- to three-hour window.

One caution: if two people in the family give two different times, don't split the difference. Take the one that comes from a record — otherwise you have simply invented a new guess and started believing it.

A straight word about “birth time rectification”

In some places the time is worked backwards through rectification — reconstructing it from past events such as a marriage, a job, an illness. It is a traditional method and it has its place.

But honestly: the result is an estimate, not a measurement. Different astrologers can arrive at different times, and the method assumes the rules of astrology are already correct. So we do not slip a rectified time into your chart. If that route is ever taken, it should be done separately and stated clearly — that this is a derived time, not a recorded one.

So what is a kundli without a time actually good for?

Quite a lot. The Moon's sign (when it holds steady), the nakshatra, which signs the planets occupy and how they relate to one another — these speak to temperament, mind, and the broader colours of a life. That is not a small thing.

What you won't get is house-based reading — “Saturn in the tenth, hence delay in career”, or “the lord of the seventh”. All of that stands on the lagna, and the lagna does not stand without a time.

Our view is simple: half a thing, given as half a thing, is better than a false claim to the whole.

Frequently asked

Can a kundli be made without the birth time?

Yes. The planets' signs will still be right, but the lagna and all 12 houses will not be reliable. The lagna shifts about one degree every 4 minutes, so guessing the time changes the whole chart.

Is assuming midnight acceptable?

No. It is a guess that quietly enters the chart. Assuming midnight can produce a completely different lagna and houses — and the reader usually has no idea they are reading a guess.

Which parts stay correct without a time?

Usually the planets' signs. The Moon's sign and nakshatra sometimes give two options, because the Moon covers around 13 degrees in a day. Our tool compares three moments and tells you clearly which values are stable and which are not.

Can the dasha be read without a time?

Only when the Moon's nakshatra stays the same across that whole day. Vimshottari dasha begins from the nakshatra — if two are possible, so are two sets of dates, so we withhold it.

I only want my Moon sign — do I need the time?

Usually not. The Moon sign rarely changes within a day — but it can, if it was near a boundary. That is exactly why the tool checks three moments instead of assuming.
