Namkaran (नामकरण), the naming of a child, is the samskara families plan most and need a muhurat for least. On its own day it needs none; what the family really looks for is the first letter of the name, which the books take from the Moon's nakshatra at the birth.
This guide covers both. It explains when a naming needs a muhurat and when it does not, gives all 108 name syllables with a worked example, explains why printed tables sometimes differ, and sets out the rules for a later naming.
When Is Namkaran Done?
Muhurta Chintamani's Samskara prakarana puts the naming on the 11th or the 12th day of life (the birth day counted as the 1st). The Manusmriti gives the 10th or the 12th, and B.V. Raman's Muhurtha the 10th, 12th or 16th. Many families name the child on the day the birth's impurity period (sutak) ends, which differs from family to family; that day is the family's own.
On that prescribed day no muhurat is needed. Muhurta Chintamani says so, and published calendars repeat it. The days are usually counted with the birth day as the first, so a child born on 12 January 2027 has its 11th day on 22 January and its 12th on 23 January. Neither date needs to be on a muhurat list.
A muhurat matters when the naming is done later — after a hospital stay, a journey, or simply when the family can gather. The rest of this guide's rules are for that case.
The Rules for a Later Naming
Muhurta Chintamani's Samskara prakarana, as published calendars apply it:
- Tithi: Pratipada, Dwitiya, Tritiya, Panchami, Saptami, Dashami, Ekadashi, Dwadashi or Trayodashi of either half — the nine published calendars list. The book asks only for no parva and no rikta tithi, which would also allow Shashthi.
- Weekday: Monday, Wednesday, Thursday or Friday.
- Nakshatra: the fixed, soft, swift and movable stars — Rohini, the three Uttaras, Mrigashira, Chitra, Anuradha, Revati, Ashwini, Pushya, Hasta, Punarvasu, Swati, Shravana, Dhanishtha and Shatabhisha.
- The hour: the forenoon is best and midday middling, Brihaspati says, quoted in Muhurta Chintamani; the afternoon and the night are left out, so the lists end where Aparahna begins, three fifths into the daytime, as published calendars end a naming.
- The lagna: only the hours whose rising sign is not movable — never Mesha, Karka, Tula or Makara — with the 8th house empty and no malefic in the lagna or aspecting it, as published calendars apply it; they read the 8th by the seven grahas, and so does the calendar view, while the strict view counts Rahu and Ketu there too.
- The season: none in the calendar view — published calendars print a late naming in either half of the year and call Uttarayana advisable; the strict view keeps it to Uttarayana, as Kashyapa asks in the Piyushadhara commentary, and also leaves out the Sun's, Saturn's and Mars' signs rising.
- Never a kshaya tithi (one current at no sunrise at the place) and never the star's varjyam — its tyajya ghatis, four of the star's sixty parts after the count the book gives for it (Muhurta Chintamani, Vivaha prakarana).
- Not weighed: the combustion of Venus or Jupiter (the commentary), and, by published calendars, Chaturmas and Holashtak.
- Closed: the day of a sankranti or an eclipse, by Garga's rule quoted in the same chapter — no auspicious act then, "even at its due time".
How the Name Letter Is Found
The zodiac's 360° holds 27 nakshatras of 13°20′ each, and each nakshatra four padas (quarters) of 3°20′. Each of the 108 padas has one syllable, and the child's name traditionally begins with the syllable of the pada the Moon was in at the birth. The table is the shatapada chakra, "the wheel of a hundred feet": Jyotisharka's verses, quoted in the Piyushadhara commentary on Muhurta Chintamani's Samskara prakarana.
So the letter needs the birth nakshatra and its pada — and the pada needs the birth time. The Moon crosses one pada in about six hours on average, so two children born on the same day can have different letters. A kundli gives the nakshatra and pada at once: the free kundli shows them for any birth time and place.
