12 Day Stars Method Of Date Selection

The 12 day stars (十二值日星) is one of the most basic methods of selecting auspicious and inauspicious dates to undertake activities.

It states that 12 stars (or gods) take turns to rule each day in an endless cycle.

With an underlying meaning to each star, it determines what particular day would be most suitable to take on or avoid certain activities.

It must be noted that the 12 day stars method of date selection is a subset of a bigger and wider Chinese metaphysical concept known as the Huang Dao Ji Ri (黄道吉日).

The dozen stars are individually named according to 12 types of chi and correlate to the 12 animal zodiac signs.

And please, do not confuse these stars with flying stars feng shui.

For simplicity and easier reference, they are labeled as D# in this exercise. The zodiacs will take the usual E# as they are found on the 24 mountains.

As always with methods of date selection, there must be a way to plot energy variables into each day on a calendar.

While we are pampered with ready-made calendar schedules of energy forces these days, a simple manual way to map out the day stars to the calendar is to note that the day zodiac that matches the month zodiac will result in the presence of D1 (jian).

When D1 is identified, then it is just a matter of tabulating the rest of the day stars according to their sequence.

Be mindful that the first days of the month in Chinese calendars do not match that of the Gregorian calendar.

And the first month of the year tend to fall in early February of the western calendar, which will be a Tiger month according to Chinese animal zodiac signs.

For ease of comprehension, below is a reference table you can use to find specific day stars.

Remember the legend as stated previously.

Let’s take for example that we intend to plot the day stars schedule for August 2019. As August is of the zodiac Z7 (Monkey), referencing the Hsia calendar we find one of the days in August where Z7 is present is on the 15th of August 2019. This means that D1 will reside on this day. By following the sequence of stars this piece of information would be sufficient to plot the day stars for the whole of August 2019.

If one intends to get into an important business contract, the 15th would be a good day as it is a D1 day, but the 21st would be a bad day as it is a D7 day.

At this point, it is important to give a brief explanation of what each individual day star represents according to the books.

This is so that one will be able to judge whether a particular day with a specific star would be a good or bad day for certain activities. Then select a date that is most suitable.

Before we go on, it is of paramount important to realize that while the following elaboration might describe activities suitable to be undertaken in certain days, classical text does not specifically mention them.

It’s just that energies present for the days are judged to be ideal for certain activities to take place.
