无聊之作-生日阴历阳历重合日期
今天是我的阴历生日和我女票的阳历生日重合之日，决定一起过生日
于是想到到底会有几次这样的日子的产生，因此在网上查到了用python做阳历到阴历转换的代码，拿来用
阳历转阴历代码来自：https://www.jianshu.com/p/8dc0d7ba2c2a
至于重合日期就很好计算了
1、自己的阴历生日和阳历生日重合
def self_birthday_overlapping(_date):
print("阳历：" + str(_date) + ";阴历：" + getCnDate(_date))
print("---------------------")
print("阴历阳历重合日期：")
cnMonth=getCnMonth(_date)
cnDay=getCnDay(_date)
for i in range(1,100):
date=datetime(_date.year+i,_date.month,_date.day)
#print(date)
month=getCnMonth(date)
day=getCnDay(date)
if cnMonth==month and cnDay==day:
print(date)
print("---------------------")也就是输入阳历出生日期的datetime，然后计算出生日期的农历，然后再根据出生日期往后100年，每年的这个日期计算农历，看看是不是和出生当年的农历相同
2、别人（女票）的阳历/阴历和自己的阴历/阳历重合日期
def two_birthday_overlapping(date_a,date_b):
cn_month_a=getCnMonth(date_a)
cn_day_a=getCnDay(date_a)
cn_month_b=getCnMonth(date_b)
cn_day_b=getCnDay(date_b)
print("a 阳历："+str(date_a)+";阴历："+getCnDate(date_a))
print("b 阳历：" + str(date_b) + ";阴历：" + getCnDate(date_b))
print("---------------------")
print("a的阳历与b的阴历重合")
for i in range(1,100):
date=datetime(date_a.year+i,date_a.month,date_a.day)
month=getCnMonth(date)
day=getCnDay(date)
if cn_month_b==month and cn_day_b==day:
print(date)
print("---------------------")
print("b的阳历与a的阴历重合")
for i in range(1, 100):
date = datetime(date_b.year + i, date_b.month, date_b.day)
month = getCnMonth(date)
day = getCnDay(date)
if cn_month_a == month and cn_day_a == day:
print(date)
print("---------------------")也就是输入a和b的出生阳历日期，计算出生日期的农历，然后分别对a的阳历和b的阴历，a的阴历和b的阳历进行匹配，得到最终的重合日期
当然，只有两个人的生日日期相近才有几率出现这种情况，大家可以尝试一下
