可以在datetime模块中创建计数器吗？

import datetime

class Counter:
    def __init__(self, start_date):
        self.start_date = start_date

    def get_current_count(self):
        current_date = datetime.datetime.now().date()
        delta = current_date - self.start_date
        return delta.days

# 示例用法
start_date = datetime.date(2022, 1, 1)
counter = Counter(start_date)
current_count = counter.get_current_count()
print(current_count)
