Beyond marriage: partners, friends, colleagues

Four classical factors compared for two people, each shown with its result, reasoning and source. There is no combined score.

Please read: what this can and cannot tell you

These are traditional indicators, not predictions. They cannot tell you whether a partnership, friendship or working relationship will succeed.
The factors come from the rules used in marriage matching and general Jyotish; applying them to other relationships is a traditional extension, and teachers weigh them differently.
No percentage or overall verdict is given, because the classical texts give no rule for combining these factors outside marriage.
Without an exact birth time the Lagna factor is unavailable, and the Moon may have changed nakshatra or sign during the birth day.

Relationship Used only as a label: the same classical factors apply to every relationship type.

The factors and their sources

Moon-sign lords (Graha Maitri): The natural friendship of the planets ruling the two Moon signs, looked at from both sides.
Source: Brihat Parashara Hora Shastra ch. 3 (natural relationships); Graha Maitri table of Muhurta Chintamani, Vivaha prakarana
Tara between janma nakshatras: Counting the nakshatras from one person's janma nakshatra to the other's gives one of nine Taras. Vipat (3), Pratyak (5) and Vadha (7) are unfavourable; Janma (1) is mixed.
Source: Tara bala, Muhurta Chintamani (nine Taras); the same count as the Tara (Dina) koota
Mutual placement of Moon signs: How many signs apart the two Moon signs are. The 6/8 (shadashtaka) and 2/12 (dwirdwadasha) relations are listed as unfavourable.
Source: Bhakoot rule, Muhurta Chintamani, Vivaha prakarana (2/12 and 6/8); Brihat Parashara Hora Shastra (trikona houses)
Lagna lords: The natural friendship of the planets ruling the two ascendants. Needs the exact birth time of both people.
Source: Brihat Parashara Hora Shastra ch. 3 (natural relationships)

The texts do not prescribe separate factors for business, friendship or work, so the same factors are shown for every relationship type. Traditions vary.
