ITYM datetime.datetime(2003, 12, 31).

I think that this way is less prone to typos like the one above:

import datetime
year = 2003
d1 = datetime.date(year, 1, 1)
d2 = datetime.date(year + 1, 1, 1)
print (d2 - d1).days

Better yet, write them out as constants if they're referenced more
than once. In that case, if the planet gets knocked into a new orbital
and rotational pattern, you can update accordingly if you,
civilization, and Python all still exist.
