计算八字的算法研究
本文用python的代码实现了计算八字，这是自己开发的，开放出来供大家研究学习。
以下也是基于jupyter notebook导出的，所以，保持原样，可读性更高。如果不是技术开发人员阅读可能会有些障碍，不过，那就pass掉代码块就行了。
首先，要想算出准备八字，就要搞清楚临界点的问题。比如，2024年是甲辰，但当输入2024.1.1时，输出却变成了“癸卯甲子甲子甲子”。这是为什么，因为，目前农历（阴历）还未过2023年。所以，在计算时要先把年从阳历转成阴历。
所以，先从这个小算法开始。
from lunardate import LunarDate
from datetime import datetime
def convert_solar_to_lunar(year, month, day):
solar_date = datetime(year, month, day)
lunar_date = LunarDate.fromSolarDate(solar_date.year, solar_date.month, solar_date.day)
return lunar_date
solar_year = 2024
solar_month = 1
solar_day = 1
lunar_date = convert_solar_to_lunar(solar_year, solar_month, solar_day)
print(f"阳历 {solar_year}-{solar_month:02d}-{solar_day:02d} 对应的农历是 {lunar_date.year}年{lunar_date.month}月{lunar_date.day}日")
阳历 2024-01-01 对应的农历是 2023年11月20日
