Compare two birth charts to see how the bond between them actually works.
This reads friendship the way classical astrology does - from two birth charts rather than two names. It compares the natural and temporary friendship between your ruling planets, the relationship between your Moon signs, and the 11th house, which is the house of friends and gains. You will need the date, time and place of birth for both people.
Most online friendship quizzes ask for two names. They add up the letters, run a fixed formula, and hand back a percentage. Nothing in that number came from the sky. A chart-based reading asks for something harder: the date, the exact time, and the place of birth for both people. Those three details are what fix the position of every planet at the moment each person was born.
The real difference is in what the number is made of. Change the spelling of a name and the letter score changes with it. A nickname gives one figure, the full legal name gives another. Planetary positions do not move when you change what you are called. They were settled by the clock and the calendar on the day, and they stay settled.
This also changes the kind of question you are able to ask. A letter score gives you one figure and nothing behind it. Two charts give you separate layers: how the planets rate each other, where each Moon sits, what the house of groups and gains holds in either chart. A single percentage hides any disagreement between those layers. Separate layers let you look at it.
Graha maitri, the friendship between planets, does not rest on one list. There are two rankings, and both are in use at the same time. The first is naisargika, meaning natural or permanent. It is a fixed table that rates each pair of planets as friend, neutral or enemy. Whatever the chart in front of you, the same pair carries the same natural rating, and nothing about a particular birth alters it.
The second ranking is tatkalika, meaning temporary. It is worked out from where the planets actually sit relative to each other in the chart being read. Counting from one planet, another standing in the 2nd, 3rd, 4th, 10th, 11th or 12th sign from it is its temporary friend. Any other position makes the two temporary enemies. Move the same pair of planets into different signs and this rating flips.
The two rankings are then combined, and the result is a five-fold compound relationship: great friend, friend, neutral, enemy, great enemy. That compound is the rating a careful reading works with. A pair that is permanently cordial but temporarily placed as enemies does not read the same as a pair that is cordial on both counts. Reporting only the fixed table, as quick tools often do, throws away half the method.
The eleventh house is the classical seat of friends, groups and gains. Read it and you are asking about scale and reach: the network a person collects, the people who arrive through other people, what comes back from that circle. It is a wide-angle view. It says very little about how one particular evening between two specific people actually feels.
The Moon answers the narrower question. It stands for the mind and the feeling, so a Moon sign describes temperament: the pace at which someone settles, what steadies them, what unsettles them. Two people can share a large overlapping circle and still find each other's company tiring. Two others can have almost no group in common and be easy together from the first hour.
Keep the two questions apart instead of merging them. Ask the eleventh house about breadth and ask the Moon about texture. When the two point in different directions, treat that as information rather than as a fault in the chart. A bond that works one to one but thins out in a crowd looks quite different on paper from one that only exists inside a shared group.
Averaging is where most readings go wrong. Everything gets flattened into one score, and the average buries the very thing that was worth knowing. Layers disagree with each other. That disagreement is the finding, not noise to be smoothed away. Two charts almost never return a clean verdict in every layer at once, and there is no good reason to expect them to.
Mixed compound ratings are normal. Some planet pairs come out as great friends while other pairs come out as enemies, inside the same two charts. These do not cancel each other out. They describe a bond that runs easily in some areas and takes effort in others, and which areas those are depends on which planets are involved and on what each of them governs in the two charts.
Where the layers do line up, with the Moons comfortable together, the house of groups well supported in both charts, and the compound ratings mostly on the friendly side, the reading is simply more confident. Agreement raises confidence. It does not promise anything. The tradition describes tendencies attached to placements, and two people still decide, day by day, how they treat each other.
Does this work with just our names?
No. Name-based friendship games are a different thing entirely and have no basis in the classical system. This tool uses real birth charts, so it needs the date, time and place of birth for both people - which is also why the result says something specific rather than generic.
What is graha maitri?
Graha maitri is planetary friendship - the classical texts rank every pair of planets as friend, neutral or enemy, both permanently and by their temporary positions in a given chart. Comparing the two chart rulers on that scale is the core of this reading.
Why does the 11th house matter for friendship?
In the classical house scheme the 11th governs friends, groups and gains. Its condition in each chart, and how each person's planets fall across the other's 11th, is read for how the friendship functions and what each person draws from it.
