如何获取从给定日期开始的月份剩余天数

import datetime

def get_remaining_days(start_date):
    current_date = datetime.datetime.now().date()
    last_day_of_month = datetime.date(start_date.year, start_date.month, 1) + datetime.timedelta(days=32)
    last_day_of_month = last_day_of_month.replace(day=1) - datetime.timedelta(days=1)
    remaining_days = (last_day_of_month - current_date).days + 1
    return remaining_days

# 示例调用
start_date = datetime.date(2022, 1, 15)
remaining_days = get_remaining_days(start_date)
print("从给定日期开始的月份剩余天数：", remaining_days)
