查找天数中的月份差异

import datetime

def calculate_month_difference(date1, date2):
    year_diff = date2.year - date1.year
    month_diff = date2.month - date1.month

    if date2.day < date1.day:
        month_diff -= 1

    total_months = year_diff * 12 + month_diff
    return total_months

# 示例用法
date1 = datetime.datetime(2022, 1, 15)
date2 = datetime.datetime(2023, 5, 20)
month_difference = calculate_month_difference(date1, date2)
print("月份差异：", month_difference)
