To read monthly luck in Zi Wei Dou Shu, the first step is to find the monthly palace, the palace treated as the "Ego palace of the month" for that reading. This is where many beginners get stuck, because there is not one way to set it but several. This guide covers the general principle, the most common methods, and the monthly flowing stars, so you understand the mechanism instead of following a hunch.

What Is the Monthly Palace?

The monthly palace is the palace that stands for one month of the year. Each year has one palace treated as the annual Ego palace (the year's own focus), and in the same way, each month inside that year gets one palace treated as the Ego palace of that month.

Once the monthly palace is set, you look at the stars sitting in it and the stars casting into it, plus the flowing stars of that month, to read the tone of the month. That is why getting the right palace is the foundation: if this step is off, everything read afterward drifts with it.

In short: The monthly palace is the palace treated as the "Ego palace of the month." Setting it correctly comes before reading the tone of the month.

Common Ways to Set the Monthly Palace

In practice, there are about six or seven methods across different schools. Below are the most common directions, explained at the level of principle.

Where it starts	Principle
From the annual palace	Use the year's own palace as the base, then count out to the palace of each month
From the Grand Duke palace	Use the palace where the year's Grand Duke sits as the base for counting the months
From the Tiger palace	Some methods always start from the fixed Tiger palace

The two methods most people regard as standard and common are starting from the annual palace or the Grand Duke palace, then counting backward by birth month and forward by birth hour to land on the monthly palace. Because the method depends on the birth month and birth hour, the monthly palace is different for each person, even within the same calendar month.

One thing to keep in mind: since there are several schools, check which method a source uses when you consult it, and avoid mixing several methods in a single reading.

In short: There are several ways to set the monthly palace. The most common start from the annual palace or the Grand Duke palace, then count by birth month and hour, so the monthly palace differs from person to person.

The Flowing Stars of the Month

Finding the monthly palace is only half the job. The other half is the flowing stars of the month, which are added to make the reading more detailed.

When you read a monthly palace, a group of flowing stars for that month is laid over the chart. When these stars land in the monthly palace, or overlap with strong stars already in the natal chart, they tend to bring out the tone of that month more clearly. That is one reason some months pass quietly while others clearly "have something going on."

In short: After setting the monthly palace, add the month's flowing stars. When they overlap strong natal stars, the tone of the month tends to show up more clearly.

Why This Step Trips People Up

Setting the monthly palace by hand is fiddly for beginners. There are many methods, and it is easy to mix up the forward and backward counting steps. Quite a few people place the monthly palace wrongly from the start without noticing, and then the reading for the whole month drifts.

This is where a tool helps. If you would rather skip the fiddly counting and go straight to understanding what a month may mean, HOROS works out the monthly palace and the month's flowing stars on your own chart, so your attention goes to the meaning instead of worrying about a misplaced palace.

Conclusion

Setting the monthly palace correctly is the first step in reading monthly luck. Four points to remember:

1. The monthly palace is the "Ego palace of the month" and is set before any reading.
2. There are several methods, and the most common start from the annual palace or the Grand Duke palace.
3. It depends on birth month and birth hour, so each person's monthly palace is different.
4. Add the month's flowing stars for a more detailed reading, especially when they overlap strong natal stars.
