(1) When arranging astrolabes, people born in leap months will be pushed to the next month. For example, if he was born in a leap month, then he will be pushed to the chart of February, and February after the leap month will still be considered as February; May leap is June, June is June, and so on.
(2) When calculating the Ryutsuki, the leap month is divided into two parts every leap month, and the first half of the month is from the first day of the first month to the fifteenth day of the first month, which is the last month, so as to find out good or bad luck; From 16 to 30, we can see the good and bad luck next month.
People born in leap months will have poor accuracy, and some schools also use this rule to push charts. I also advocate that this method can be used when it is not practical.
If you were born on the third day of leap May, there are two algorithms. Maybe in May or June, right? But the plate discharged in this way is completely different. What shall we do, or shall we basically take June as the benchmark? If there is any deviation, it will be May?
Well, the arrangement of dishes is different. For example, those born before May 15 can arrange dishes in May, and those born after May 16 can arrange dishes in June.
