Birth Chart Compatibility


Can something that seems as random as your birthday really have any bearing on whether or not you and your mate are compatibility?

While the idea of birthday compatibility may seem silly to some, there are many people who believe the day that we were born has a huge bearing on our personality, our life path and who we should date or marry.


According to astrology your zodiac sign has a great deal to do with how your life turns out.  If you have ever had your horoscope come true, then you may just be a believer in astrology.   Birthday compatibility is just another way that astrologers can decide your fate based on the Zodiac.

In order to decide if you are compatible with your boyfriend, girlfriend, husband or wife then you must first figure out each of your signs.  The chart below will help with that.

Numerology is another way to decide birthday compatibility.  In order to decide whether you are compatible according to numerology, you need to first calculate your life path number.

You do this by reducing all the segments (day, month, year) of your birthday to single digit numbers and then reduce that number to a single digit. It is easiest to explain with example.

Say your birthday was: 11/8/1984

You would first add up the month:

1 + 1 =2

Then, add up the day:

In this case, you don?t have to add anything up.  Your single digit is 8.

Next, add up the year:

1 + 9 + 8+ 4 = 22

2 + 2 = 4

So, now that you have each segment reduced down to single digits you must add all of them up and reduce them to a single digit:

2 + 8 + 4 = 14

1 + 4 = 5

Your life path number in this example would be 4.

Once you have done this for you and your partner, check out the chart below to see if you are compatible.
