What is Tara Balam & Chandra Balam?
Tara Balam and Chandra Balam are two fundamental pillars of Muhurta (Vedic electional astrology). Tara Balam measures the strength of the day's Nakshatra relative to your birth Nakshatra, while Chandra Balam measures the strength of the Moon's transit relative to your birth Moon sign (Rashi). Together with Lagna Shuddhi (ascendant purity), they determine whether a given day is auspicious for you.

How to Calculate Tara Balam & Chandra Balam – Step by Step
Understanding the calculation helps you verify results and use this Muhurta tool with confidence. Here is the simple Vedic method:
Count from Birth to Daily Nakshatra
Count from your birth Nakshatra to the daily Nakshatra, both inclusive. For example, if your birth Nakshatra is Jyeshtha (18) and today's Nakshatra is Purva Bhadrapada (25), the raw count is 8 (25 − 18 = 7, +1 = 8).
Divide by 9 to Get Tara
Divide the count by 9 and take the remainder. If the remainder is 0, treat it as 9. So 8 ÷ 9 = remainder 8 → Mitra Tara. The 9 Taras are: Janma (1), Sampat (2), Vipat (3), Kshema (4), Pratyak (5), Sadhana (6), Naidhana (7), Mitra (8), Parama Mitra (9).
Check Moon Transit (Chandra Balam)
Count from your birth Rashi to the daily Moon Rashi. The 4th, 8th, and 12th positions are considered inauspicious (Ashtama Chandra is the worst). All other positions are neutral or auspicious.
Verify Lagna Shuddhi
The event's Ascendant (Lagna) should ideally be a benefic sign — Taurus, Gemini, Cancer, Virgo, Libra, Sagittarius, or Pisces. Malefic planets (Sun, Mars, Saturn, Rahu, Ketu) in the 1st house spoil the Lagna.
Combine All Three Factors
A muhurta is auspicious only when the Tara Balam is good (Sampat, Kshema, Sadhana, Mitra, Parama Mitra), Chandra Balam is not 4/8/12, and the Lagna is clean.

Why Tara Balam & Chandra Balam Matter in Muhurta
In Vedic astrology, no auspicious event should be started without checking the Tara Balam and Chandra Balam of the people involved. Even if the day's Panchang looks perfect, an unfavorable Tara (like Janma, Vipat, Pratyak, or Naidhana) can bring obstacles, delays, or unwanted results. Similarly, the Moon's transit in the 4th, 8th, or 12th house from your birth Rashi causes mental stress, health issues, and financial loss. This is why traditional pandits always ask for the birth Nakshatra and Moon sign of both the bride and groom before fixing a marriage date.

Frequently Asked Questions
Tara Balam is the strength of the day's Nakshatra relative to a person's birth Nakshatra. It is counted from the birth star to the daily star and divided by 9. The nine Taras are Janma, Sampat, Vipat, Kshema, Pratyak, Sadhana, Naidhana, Mitra, and Parama Mitra. Good Taras are Sampat, Kshema, Sadhana, Mitra, and Parama Mitra.
Chandra Balam refers to the position of the Moon's transit relative to a person's birth Moon sign. The 4th, 8th, and 12th positions are considered inauspicious. The 8th position, known as Ashtama Chandra, is the most harmful and should be strictly avoided for any auspicious event.
Lagna Shuddhi (Read More) means the Ascendant (Lagna) of the event should be a benefic sign and should not have malefic planets like Sun, Mars, Saturn, Rahu, or Ketu in the 1st house. If any of these malefic planets are in the 1st house, the Lagna is considered impure and the muhurta is spoiled.
Yes, this calculator is designed for exactly that. Enter the birth Nakshatra and Rashi of the bride and groom, the daily Nakshatra and Moon Rashi, and the marriage Lagna. The tool instantly gives you a joint verdict on whether the day is auspicious for the couple.
Auspicious Taras: Sampat (2), Kshema (4), Sadhana (6), Mitra (8), Parama Mitra (9).
Inauspicious Taras: Janma (1), Vipat (3), Pratyak (5), Naidhana (7). These should be avoided for important events.
For a joint muhurta like marriage, both persons should have favorable Tara and Chandra Balam. If one person has an unfavorable Tara or Chandra Balam, the event is considered inauspicious for that individual, and it is best to choose a different date.
