python - What is the range of valid dates for the datetime module?

Question

I'm playing with the Python datetime module. I'm using it to determine the day of the week for a given date. Python conveniently raises a ValueError when the date is invalid; e.g., for February 29 on non-leap years.

I have found that for years greater than 10,000 AD, ValueError exceptions are raised for many dates that are not February 29. This leads me to consider that the datetime module is not valid for dates that far in the future.

What is the range of valid dates for the datetime module?

Answer 1

Check date.min and date.max:

>>> from datetime import date
>>> date.min
datetime.date(1, 1, 1)
>>> date.max
datetime.date(9999, 12, 31)
