Friendship Compatibility by Date of Birth — How Strong Is Your Friendship?

Friendship compatibility by date of birth combines two old systems that both start from the day you were born. Numerology gives three numbers from the date: the life path (the whole date reduced) describes where your life is heading; the birthday number (the day reduced) describes a natural talent; the attitude number (day plus month) describes your first reaction to people and situations. Astrology adds the sun sign for the date - computed here in the sidereal (Vedic) zodiac - and its element: fire, earth, air or water.

The calculator compares each of these between you and your friend and weighs them into a friendship compatibility percentage. Life path carries the most weight because friends who are heading the same way in life stay close; the sun sign element comes next because it shapes temperament - how you like to spend time and how you handle stress.

Add your names and the expression number joins the comparison, which is useful if you want to see how you work together on projects, trips or a shared business.

In a friendship numerology calculator, each life path has a recognisable style of friendship, and some combinations click immediately. The table gives each style and the life paths it usually gets along with best.

Sun sign friendship compatibility is read through the elements. Friends of the same element share a temperament; fire and air feed each other (ideas and energy), earth and water support each other (stability and feeling). Fire with water and earth with air are opposites - they can learn a great deal from each other but need patience.

The signs used for sun sign friendship compatibility here are sidereal (Vedic), which run about 24 days behind the Western dates. If you know your Western sign, you may find your Vedic sun sign is the one before it - the calculator works it out exactly from your date.

A best friend compatibility test is most fun when you take it together. Enter both dates of birth, look at the gauge, and then go through the aspect table: where your life paths match you will probably recognise the shared direction; where your attitude numbers differ you will recognise the classic argument - one of you decides in a second, the other needs a day.

The friendship compatibility percentage is not a score to pass or fail. Friendships with opposite numbers often last the longest, because each friend brings what the other lacks: the planner and the free spirit, the talker and the listener. Use the "best things to do together" card for ideas that suit both your numbers - and share the result with your friend.

The same calculator works for siblings, room-mates, colleagues and team-mates. For a romantic partner, try the name compatibility and love compatibility calculators, which look at the relationship side of the numbers and the charts.

Here is a real run of the best friend compatibility test for two friends, one born on 14 August 1990 and the other on 3 February 1992. These are the numbers the calculator finds and how it combines them.

How the numbers come out. Friend A: the day 14 gives 1 + 4 = 5, the month is 8, and the year 1990 gives 1 + 9 + 9 + 0 = 19, then 1 + 9 = 10, then 1. The life path is 5 + 8 + 1 = 14, which reduces to 5. Friend B: day 3, month 2, and the year 1992 gives 21, which reduces to 3, so the life path is 3 + 2 + 3 = 8. The Sun was in sidereal Cancer on 14 August 1990 and in sidereal Capricorn on 3 February 1992.

How the percentage is built. Each aspect gets a match score, and the scores are weighted: 75 x 35% + 65 x 20% + 75 x 15% + 80 x 30% = 74.5, shown as a friendship compatibility percentage of 74 - "great friends". The life path pair 5 and 8 is a friendly one; the water and earth elements support each other.

How to read it. In friendship styles by life path number, 5 is the adventurer and 8 the achiever. The result suggests road trips and new experiences from one side and shared goals and planning from the other - two different styles that fit together rather than mirror each other. That is typical of a high score built on complementary numbers rather than identical ones.

The friendship compatibility percentage falls into four bands. None of them is a pass or a fail - they describe how much effort the friendship takes, not whether it is worth having.

• 80% and above - best friends material. Your numbers and elements line up closely. These friendships feel easy from the start.
• 65 to 79% - great friends. Most aspects agree and the rest complement each other. This is where most close friendships land.
• 50 to 64% - good friends with effort. Some aspects pull in different directions. Knowing each other's friendship style smooths the rough edges.
• Below 50% - opposites. You see the world differently. These friendships can be the most rewarding when both people value the difference.

Two details explain most surprises. The life path carries the most weight, so two friends with matching life paths score well even if their sun signs clash. And sun sign friendship compatibility uses the Vedic (sidereal) sign, which is often one sign earlier than the Western sign you know - so check the sign the result shows before reading the element advice.

If you run the friendship numerology calculator for a whole group, compare each pair separately.

The friendship numerology calculator compares two people at a time, but it works for any pair, not only best friends.

• A friend group. Run every pair. Friendship styles by life path number show who plans, who listens and who brings the fun, which explains a lot about how the group works.
• Siblings. Brothers and sisters can have very different numbers. The friendship numerology calculator shows where the differences come from, which often makes them easier to live with.
• Colleagues and team-mates. A best friend compatibility test between colleagues is really a working-style check: the attitude number shows how fast each of you reacts, and the life path shows where each of you is heading.
• Room-mates. Here sun sign friendship compatibility is the useful part: friends of the same or supporting elements fall into daily rhythms more easily.

Whatever the pair, read the friendship styles by life path number card for both people first. It says more about how to treat each other than the friendship compatibility percentage does, and it is the part people remember. The friendship numerology calculator is free and needs only the two dates of birth.

1. Numbers from the dates. The friendship numerology calculator finds the life path (day, month and year reduced separately, keeping 11, 22 and 33), birthday number and attitude number for each of you.

2. Sun sign from the sky. The Sun's sidereal position on each date is computed with the Swiss Ephemeris and placed in its sign and element.

3. Weighted match. Life path 35%, sun sign element 30%, birthday number 20%, attitude number 15% - with names, the expression number joins at 15%. Every aspect is shown in the result.

In sun sign friendship compatibility, each sign has its own way of being a friend and a few signs it gets along with most easily. These are sidereal (Vedic) sun signs - the calculator finds yours from your date of birth.

Knowing friendship styles by life path number is useful mainly for one thing: giving friends what they need, not what you need. A 1 wants to feel respected - ask for their opinion and credit their ideas. A 2 wants to feel safe - check in, remember the small things, avoid sarcasm. A 3 wants fun - make plans, laugh at their jokes, keep things light when they are stressed.

A 4 wants reliability - be on time, keep your word. A 5 wants freedom - do not take it personally when they disappear for a week; invite them to something new. A 6 wants to feel appreciated - say thank you for the meals and the care, and look after them in return.

A 7 wants depth and privacy - have the real conversation and keep their secrets. An 8 wants respect for their ambition - support their goals and book time with them in advance. A 9 wants shared values - be kind to others in front of them and they will be kind to you for life.

Run the friendship numerology calculator with your closest friends and read their friendship style card; it is a small key to a big part of their personality.
