Each person has his or her own personal archetypal tarot card determined by birth date. This card reflects your personality and outlook, as well as your potential---qualities that will be helpful for you to develop throughout your life.
There are different systems for calculating your birth card. I recommend this easy method.
Take each digit of your birth date and add them together.
If the resulting number equals 22, such as in the first example, keep it. Your birth card is The Fool. If the resulting number is a double digit other than 22, add the digits together to reduce the number.
In the last two examples above,
If the resulting number is a double digit other than 22, reduce it again. For example, May 24, 1952 must be reduced twice like this:
Each reduced number, corresponds with a Major Arcana card as follows:
1 = The Magician
