好的,我可以回答您的问题。首先,我们需要知道每个月份的天数,然后将实际的天数减去已经过去的天数,就可以得到缺失的天数。
以下是利用Python编写的示例代码:
```python
import datetime
def missing_days(year, month):
days_in_month = {1:31, 2:28, 3:31, 4:30, 5:31, 6:30, 7:31, 8:31, 9:30, 10:31, 11:30, 12:31}
now = datetime.datetime.now()
if year > now.year or (year == now.year and month > now.month):
return "Invalid date"
if year % 4 == 0 and (year % 100 != 0 or year % 400 == 0):
days_in_month[2] = 29
days_passed = (now - datetime.datetime(year, month, 1)).days
missing_days = days_in_month[month] - days_passed
return missing_days
# Example usage
missing_days_in_current_month = missing_days(2021, 7)
print(f"{missing_days_in_current_month} days are missing in the current month.")
```
注意:以上代码在计算闰年时没有考虑历史上存在的例外情况。在实际情况中,请使用标准的闰年规则或逐年查询其是否闰年。
