Which is more accurate, the astrolabe or the constellation? I am ambivalent.

That depends on the specific astrolabe and constellation.

If it is accurate in time, then the astrolabe is more accurate. It is always changing. There are also 12 houses, 10 big stars, and many asteroids, which have a large amount of information. There are more deduction methods than eight characters, such as moon limit, moon limit, sun return, moon return and so on.

If the time is not very accurate, it is recommended to use eight characters, 2 hours per hour, so that the time tolerance is wider and easier to calculate.

The conclusions drawn by the two forecasting methods are more likely to intersect.

Astrolabe and astrolabe are actually probability theories summed up over thousands of years.

People's own factors can never be ignored. If you estimate that you can get married in a certain year, you are competing with fate and not getting married. Is it different from the forecast?

Fifty days, forty-nine days.
