"In the Northern Hemisphere, this marks the beginning of fall.
The bright, outward energy of summer gives way to the slower,
more introspective energy of autumn and winter.
The warmth and extroversion of the past months
make way for a time of solitude, rest, and reflection.
As the Earth turns inward, so do we.
The equinox is often seen as a bridge between two distinct energies.
Spring and summer, with their long days and abundant sunlight,
are seasons of growth, play, and connection.
These are the "Sun Seasons", when everything is in bloom,
and our energy is more expansive.
Fall and winter, on the other hand, are considered the "Moon Seasons".
As daylight fades, the moon takes center stage,
and we begin to spend more time in darkness.
This period of extended night symbolises a time for
rest, introspection, and quiet connection."
The Solstices & Equinoxes hold importance in all ancient civilisations, regardless of whether one is from the East or West. For the ancient Chinese, as the Moon takes centre stage, you may want to take note of its position in your 紫微斗数 (ZWDS) & 奇门遁甲 (QMDJ) chart.
For ZWDS, the Sun & Moon are represented as 太阳 Tai Yang & 太阴 Tai Yin. One quick way to see whether the Sun or Moon holds greater importance in your chart is to check its level of brightness, its interaction with other stars and the nature of the palace itself. Then you need to check your hour of birth manually. The reason is, the level of brightness does not take into consideration your hour of birth. If you are born closer to noon, the Sun will have more energy. If you are born closer to midnight, the Moon will have more energy. Example: let's say that the Moon in your ZWDS chart is in 陷 Xian (Dim), but you are born at midnight. Then it will not be as dim as indicated. More positive qualities of the Moon will manifest than expected in your chart. However, if you are born at noon, then the Moon will be even darker than expected.
The autumn equinox is another indication. As the Moon begins to take precedence, you might want to keep a lower profile if your Moon is weak. Conversely, you might also notice the palace where your Moon resides gaining strength. Sometimes, in a weird sort of way, both positive & negative effects are strengthened.
Some ZWDS practitioners believe that the Moon is in 化忌 Hua Ji this entire year 乙巳 Yi Si. They base this opinion on the Heavenly Stem 乙 Yi which afflicts the Moon. In addition, some also use the current month stem of 乙酉月 and see this as a double whammy on the Moon.
While I generally agree that Yi has some bad effect on the Moon this year, I have reservations about the double whammy caused by the month. This does not mean that I think it's wrong.
ZWDS runs on the Lunar calendar. The transition from one decade, year or month to another is based on the new moon which is the 1st day of the lunar month. When it comes to the analysis of annual luck, the 太岁 Tai Sui (Jupiter) stem is consistently 乙 Yi. But there is also the annual palace stem, which is different from individual to individual. It is the same for the calculation of monthly palaces. The palace stems of monthly palaces vary from individual to individual, even though they are the same for the solar calendar.
Simply put: ZWDS is a tool that is evolving. Yes, a lot of books have been written about ZWDS in both Chinese & English. But once you read them, you will also realise that a lot of knowledge has been lost & destroyed. In the olden days, many secrets were passed down by word of mouth but never written down. There is some confusion about which stem is more important or whether both should be used equally. Some prefer the solar stems. Some insist that the palace stems are important too. So ZWDS masters accumulate as many charts as possible to experiment & verify if their methods work.
The same can be said about QMDJ, perhaps even more so.
There is no 太阳 Tai Yang in a QMDJ chart. There is only 太阴 Tai Yin with 9 other deities. But the nature of 太阴 Tai Yin in QMDJ is different from ZWDS. In ZWDS, the Moon is Yin water Gui. In QMDJ, the Moon is Yin metal Xin. Its attributes / qualities are also slightly different.
Water is a lot more passive. Metal is a lot more aggressive.
