Python：返回當月第三個星期四下一次出現的日期

這就是你要找的嗎？它輸出2019-2-2 1基于今天是1/19，1月的第三個星期四是1/17。基本上使用這些其他答案進行詳細解釋。這是最初的dup評論（已刪除）-下周五如何計算？。只要問一下是否有什么需要解釋的。

import datetime

today = datetime.date.today()
next_thursday = today + datetime.timedelta(((3 - today.weekday()) % 7))
while True:
    if 15 <= next_thursday.day <= 21:
        next_third_thursday = next_thursday
        break
    else:
        next_date = next_thursday + datetime.timedelta(days=1)
        next_thursday = next_date + datetime.timedelta(((3 - next_date.weekday()) % 7))

print(next_third_thursday)
