In traditional Chinese astrology, the year pillar, month pillar, day pillar, and hour pillar form a person's "Ba Zi" (eight characters), which represent the heavenly stems and earthly branches corresponding to the year, month, day, and hour of birth. These pillars not only reflect a person's destiny and personality traits but are also closely related to health, career, marriage, and other aspects. This article will provide a detailed introduction on how to query and interpret the year pillar, month pillar, day pillar, and hour pillar, helping you gain a deeper understanding of your own astrological information.

Querying and Interpreting the Year Pillar

The year pillar refers to the heavenly stems and earthly branches representing the year of birth, marking the year in which a person was born. It is worth noting that the boundary for the year pillar is the Start of Spring, not the first day of the lunar new year. For example, a person born on the third day of the first lunar month in 1998 would have a year pillar of Ding Chou (1997) instead of Wu Yin (1998), because the Start of Spring occurred on the eighth day of the first lunar month. To query the year pillar, one needs to refer to the lunar calendar and find the corresponding heavenly stems and earthly branches using a perpetual calendar.

Querying and Interpreting the Month Pillar

The month pillar represents the solar term of the month of birth, and its correspondence with the lunar month is not based on the first day of the month but on the solar terms. For example, the first month corresponds to the Yin month, the second month to the Mao month, and so on. The earthly branch of the month pillar remains fixed each year, while the heavenly stem follows a pattern and can be determined using the "Table for Calculating the Month Stem from the Year." For instance, in the months of Jia or Ji years, the first month is Bing Yin, and the second month is Ding Mao, and so on.

Querying and Interpreting the Day Pillar

The day pillar uses the heavenly stems and earthly branches to represent the day of birth. Since the cycle of the heavenly stems and earthly branches for days lasts 60 days and is affected by the length of the month and leap years, the day stem and branch must be looked up using a perpetual calendar. The boundary for the day pillar is midnight (11 PM), which should be noted carefully when querying.

Querying and Interpreting the Hour Pillar

The hour pillar uses the heavenly stems and earthly branches to represent the hour of birth. Each hour spans two hours, making a total of twelve hours in a day. An hour table helps us understand the specific time range for each hour. The earthly branch of the hour pillar is fixed, while the heavenly stem varies, and can be determined using the "Table for Calculating the Hour Stem from the Day." For example, on a day of Bing Shen, the hour stem for the morning hour (Mao) is Xin, making it Xin Mao hour.

Rules for Arranging the Major and Minor Fates

The major fate (Da Yun) and minor fate (Xiao Yun) together form a person's entire life destiny. The major fate is determined based on the month pillar and has different directions for men and women. The calculation of the starting age for the major fate is based on the month of birth, with the direction determined according to gender. The minor fate follows a clockwise direction for male-born males and female-born females, and an anti-clockwise direction for female-born males and male-born females, starting from the hour pillar. A major fate moves one step every ten years, while the minor fate governs the fortune or misfortune of a single year.

By querying and interpreting the year pillar, month pillar, day pillar, and hour pillar, we can gain a more comprehensive understanding of our own astrological information. These pillars are not only related to personal destiny and personality, but also closely connected to health, career, marriage, and other aspects. Mastering this knowledge can help us better plan our lives and seize opportunities.
