Tara Bala and Chandra Bala: Moon-Based Strength and Choosing Auspicious Days
In Vedic astrology, the Moon is the most personal planet in Muhurta — the science of choosing the right time. Two of its most useful day-selection tools are Tara Bala and Chandra Bala. Tara Bala measures the strength of the day's nakshatra (lunar mansion) against your birth nakshatra, and Chandra Bala measures whether the Moon is in a friendly, neutral, or enemy sign for your chart.
Together they answer a practical question: is today a good day for me? The two balas are among the quickest checks an astrologer performs before approving anything — from starting a journey and signing a document to beginning a relationship or a business. They are computed from your Janma Nakshatra, the nakshatra of your Moon at birth.
This guide explains the 27 taras and the nine tara groups, how Chandra Bala works, and how to combine them to choose your best days.
What Is Tara Bala?
Tara Bala is the strength derived from counting from your birth (Janma) nakshatra to the nakshatra of the day or moment in question. Each nakshatra has a lord among the nine planets — Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, and Ketu — and each of the 27 nakshatras is assigned a tara (star) number from 1 to 9 in the cycle. The count repeats across the sky, so the same tara number returns every nine nakshatras.
The result is that a day's nakshatra belongs to one of nine taras, each with a verdict: Janma (birth) tara is mixed — good for some things but inauspicious for journeys and new beginnings; Sampat tara is excellent for wealth and beginnings; Vipat tara is unfavorable and to be avoided for important work; and so on through the cycle. The calculator counts the nakshatras for you and returns the tara and its verdict.
- Tara Bala counts from your birth nakshatra to the day's nakshatra.
- The 27 nakshatras repeat in a 9-tara cycle ruled by the 9 planets.
- Each tara has a verdict from excellent to inauspicious.
- Janma tara is mixed: good for some rites, avoid for journeys and new ventures.
The Nine Taras and Their Meanings
The nine taras in order are Janma (birth), Sampat (wealth), Vipat (danger), Kshema (welfare), Pratyari (obstacle), Sadhaka (achievement), Vadha (loss), Mitra (friend), and Parama Mitra (best friend). The first, fourth, sixth, and eighth taras — Janma, Kshema, Sadhaka, and Mitra — are favorable; the second and ninth (Sampat and Parama Mitra) are considered neutral or mildly favorable; and the third, fifth, and seventh (Vipat, Pratyari, and Vadha) are unfavorable for new beginnings.
In practice, astrologers avoid Vipat, Pratyari, and Vadha taras for important ceremonies, and prefer Sampat, Kshema, Sadhaka, and Mitra. Janma tara is nuanced: it is favorable for certain rituals and reconnecting with roots, but traditionally avoided for journeys, interviews, and inaugurations. A strong Tara Bala is one of the first green lights in a Muhurta check.
- Favorable: Sampat (2), Kshema (4), Sadhaka (6), Mitra (8).
- Neutral: Janma (1) — good for some rites, avoid for journeys and launches.
- Unfavorable: Vipat (3), Pratyari (5), Vadha (7) — avoid for important beginnings.
- Parama Mitra (9) is counted favorable by most traditions.
What Is Chandra Bala?
Chandra Bala is the strength of the Moon for a given day, judged by where the transiting Moon sits relative to your chart. The simplest and most common method is sign-based: find the Moon's sign for the day and check whether that sign's lord is friendly, neutral, or enemy to your own chart's Moon ruler. If the Moon is in a friendly sign, Chandra Bala is strong; in a neutral sign, moderate; in an enemy sign, weak.
A second method uses the Moon's nakshatra and its distance from your Janma Nakshatra. The practical rule is that strong Chandra Bala days are excellent for anything emotional or relationship-related — marriage, engagements, travel for pleasure, and beginning new friendships — because the Moon rules the mind and feelings.
- Chandra Bala judges the day's Moon sign against your chart's Moon.
- Friendly-sign Moon = strong bala; neutral = moderate; enemy = weak.
- Strong Chandra Bala favors emotional and relationship undertakings.
- It is a core check before weddings, engagements, and journeys.
How to Combine Tara Bala and Chandra Bala
The two balas are used together in Muhurta selection. A day with both strong Tara Bala and strong Chandra Bala is an excellent choice for almost any auspicious work. A day with strong Tara but weak Chandra is still workable for practical matters like starting a business, while a day with strong Chandra but weak Tara may be fine for emotional and social events but weaker for launches and deals.
When both are weak, astrologers look for a better hour within the day, because the balas can be improved by choosing a favorable nakshatra in the daytime window. This is why the calculator ranks not just days but also favorable time windows, so you can always find the best available moment even in an ordinary week.
- Strong Tara + strong Chandra = excellent for almost any auspicious work.
- Strong Tara + weak Chandra = fine for practical and business matters.
- Strong Chandra + weak Tara = fine for emotional and social events.
- When both are weak, pick a favorable hour or window within the day.
