01What is the namkaran syllable rule?
The Grihya sutras place the namkaran samskara on the eleventh or twelfth day after birth, and the rule they carry is simple: the name begins with the syllable belonging to the pada of the nakshatra the Moon stood in at the moment of birth. A nakshatra spans 13°20' and is quartered into padas of 3°20', so there are 108 padas and 108 syllables. Because the Moon crosses a full nakshatra in roughly a day and a pada in roughly six hours, the birth time decides the pada: two children born on the same date can be given letters from two different padas, and sometimes from two different nakshatras.
02How do I find the right letter for my baby?
You need the nakshatra and the pada, and both come from the Moon's longitude at the time of birth. Compute them first on the nakshatra calculator, which takes a birth date, time and place and returns the janma nakshatra with its pada and the degrees remaining. Then select them here. This page deliberately does not ask for birth details of its own: the nakshatra is the input a family usually already has, written on the janma patri or given by the astrologer at the namkaran, and asking for a birth time twice on two pages helps nobody.
When the pada is not known
Look at all four. The four syllables of a nakshatra are shown together on this page for exactly that reason, and they are all syllables of the same nakshatra. The tradition's objection is to naming from the wrong star, not from a neighbouring quarter of the right one. Where the family already has a name in mind, checking whether its first syllable appears anywhere in the four is the usual practical compromise, and it is one an astrologer will often accept.
When the birth time is uncertain
A pada is six hours of the Moon's motion, so an hour of uncertainty rarely moves it and a half-day of uncertainty usually does. If the recorded time is a rounded hour or a family memory, ask for the nakshatra to be computed for the earliest and the latest the birth could have been. Where those two give different padas, the tradition's own answer is birth-time rectification by an astrologer rather than a choice made by the parents from a table.
03Why does each pada have a different syllable?
Because the 108 syllables are a map of the whole zodiac and not a list attached to the 27 stars. Nine consecutive padas fill exactly one rashi of thirty degrees, so the syllables run through the twelve rashis nine at a time: the nine of Mesha, then the nine of Vrishabha, and so on round. That is why a nakshatra's four syllables can straddle a rashi boundary: Krittika's first pada carries A and sits in Mesha while its other three sit in Vrishabha. The page marks which rashi each pada's syllable belongs to, because that rashi is the child's naam rashi if the name is taken from it.
04What else does the nakshatra tell a family?
The classical profile of a nakshatra is four things, and all four are shown here. The ruling graha, which is also the lord of the first Vimshottari mahadasha the child will run, so a Moon in Magha means a Ketu dasha from birth. The deity, which is what the nakshatra is read through in the texts. The symbol, which is the image the older literature uses. And the gana (Deva, Manushya or Rakshasa), which is one of the classifications a matching reads years later. None of these is a statement about the child; they are the attributes the tradition assigns to the star.
05Do you suggest baby names, not just letters?
No, and that is a deliberate choice rather than a gap. The tradition gives a syllable. Everything after the syllable (the meaning, the family's language, the grandparents' claim, whether the name sits well with a surname, whether it can be spelt over a telephone) is the family's, and no list generated from a table knows any of it. Name lists on calculator pages are also, in practice, the same few hundred names recycled, which is how a naming tradition thousands of years old ends up producing four children on one street with the same name. We give the letter.
06When is the namkaran performed?
The Grihya sutras give the eleventh or twelfth day after birth as the usual day, with the tenth, the hundredth day and the first birthday all appearing in different sutra texts and different regional customs. In practice families choose a day in that window that also carries a workable muhurat: a favourable tithi and nakshatra, with the inauspicious yogas avoided. The namkaran muhurat page finds those days for a place and a month, and the daily panchang shows the underlying tithi, nakshatra and yoga for any single date.
07Is the naming syllable the same as the rashi letter?
They are two layers of the same table, and the difference is worth being exact about. The pada syllable is one of 108 and belongs to a single quarter of a single nakshatra. The rashi letter set is the nine pada syllables that share a rashi, quoted together as "Chu Che Cho La Lee Lu Le Lo A for Mesha". A family told to name a child "from the Mesha letters" has been given the nine; a family told the pada has been given the one. Naming from the exact pada syllable is the stricter reading and is what the sutra rule actually says.
08Does the nakshatra affect anything beyond the name?
In the tradition's own terms, yes. The janma nakshatra is read in several places later. It sets the starting point of the Vimshottari dasha, since the Moon's position inside the nakshatra decides the balance of the first mahadasha. It carries the gana, nadi and yoni that a kundli milan classifies decades later. And it is the star named in a sankalp. Each of those is a reading the classical texts prescribe, reported here as theirs; none of it is a claim about how a child will turn out.
