Marriage is a sacred bond that ties two souls together in a lifelong journey of harmony and love. In India, the marriage process involves several steps, including astrology. In Vedic astrology, marriage compatibility is done through 10 Porutham, of which Dina Porutham (Dina Koota) is considered very essential.

Dina Porutham, or the compatibility of the day of birth, has great significance in analysing harmony and success in long-term married life. It plays an important role in shaping a happy and prosperous married life.

What is called the Dina Porutham?

Dina Porutham evaluates the compatibility between the days of birth of the to-be bride and groom. According to Vedic astrology, each day is closely associated with a specific star and a Tithi. These stars and Tithis possess special energies and features, which tend to influence one’s personality and destiny.

Dina Porutham in a couple’s horoscopes denotes good health, wealth, freedom from disease and poverty. A compatible Dina Porutham can help a couple lead a contented and blissful married life. Hence, astrologers consider this an important feature to move forward to assess the other 9 poruthams in the couple’s horoscopes.

How to assess the Dina Porutham?

The Moon travels through 27 stars in 27 days. While counting from the female star to the male star, no remainder is left after dividing the resulting number by 9; the horoscopes are considered to have a good Dina Porutham.

When analysing the Dina Porutham, or daily compatibility, if a groom’s star is in the 2nd, 4th, 6th, 8th, 9th, 11th, 13th, 15th, 18th, 20th, 24th, or 26th star from a bride’s star, it is compatible (Uttamam). If the groom’s star falls in the same zodiac sign as the bride’s star, it is considered compatible. However, the same must not be applied to people born under the same star.

If both future partners fall under Thiruvathirai, Rohini, Hastham, Poosam, Maham or Thiruvonam stars, then the Dina Porutham is ‘Uttamam’.

Similarly, if the star count falls in the 16th position except the 3rd Patham, or in the 14th position except the 4th Patham, or in the 12th position except the 1st Patham of the birth chart, it is considered 'Madhyam’. Matches other than these are considered no match. Each star is divided into 4 Pathams. It is good for a man who is born in the Patham of the star preceding the woman.


Rasi Porutham is one of the main poruthams in Vedic astrology. It plays a vital role in analysing compatibility between to-be partners in a marriage. This ancient practice examines the alignment of the Rasi (Moon sign) of both the bride and groom to confirm harmony and challenges in their married life. Rasi Porutham is observed strictly as it is linked with the mental and emotional compatibility between the couple. A favourable match can bring harmony and understanding in married life.

How does Rasi Porutham Impact?

Rasi Porutham ensures emotional compatibility between couples and fosters understanding, mutual respect, and empathy in their relationship. A compatible Rasi Porutham between a bride and groom contributes to a fulfilling, strong marital bond with goals and emotional intimacy.

When the Rasi Porutham between a bride and groom is incompatible, it may lead to conflicts or potential challenges in their relationship. Sometimes human efforts are advised to overcome hardships and establish harmony, and sometimes the marriage itself is not recommended.

Certain Rasi combinations are considered favourable, while some may be less favourable. Astrologers conclude whether the Rasi Porutham is present between the couple based on this condition.

How is Rasi Porutham calculated?

Astrologers calculate Rasi Porutham by comparing the zodiac signs of the bride and groom. They study the distance and position between the two Rasi within the twelve zodiac signs. Some zodiac combinations are considered favourable, while others may require precise horoscope analyses. Based on this zodiac compatibility, they determine the Rasi Porutham between the couples.

Rasi Compatibility Rules

  • If the male and female have the same Rasi (zodiac sign), or if the groom's Rasi is in the 6th position from the bride’s Rasi, it is Uttamam.
  • If the groom's Rasi is the 7th sign from the bride’s Rasi, it is Sama Sapthamam.
  • If the groom's Rasi falls in the 1st, 3rd, 5th, or 12th position from the bride’s Rasi, it is Madhimam.
  • If the groom's Rasi falls in the 7th, 9th, 10th, or 11th position from the bride’s Rasi, it is Uttamam.
  • If the groom's Rasi falls in the 2nd, 6th, or 8th position from the bride’s Rasi, it is not compatible.
  • If the Rasi of the bride and groom are the same, then it is called Eka Rasi. In the case of Eka Rasi, the bride’s star should be positioned after the groom’s star.

If the groom’s Rasi is in the 6th or 8th position from the bride’s Rasi, or if the bride’s Rasi is in the 6th or 8th position from the groom’s Rasi, it is called Shashtashtaka Dosha. Astrologers will not advise such horoscope combinations for marriage.

By considering the concord between moon signs and essential compatibility, Rasi Porutham offers insights into the strengths and challenges between to-be couples.
