Problem with datetime module

[perfringo]

import datetime
   ...
    date_diff = datetime.datetime.now() - test_date
   ...
 

I was writing similar answer but was ninjad by buran :-). Very good answer and I like it.

Observation / nitpicking: it is matter of preference but one option is to use datetime.datetime.today() which is for me personally more in line with 'explicit is better than implicit'. I am not speaking english natively so for me 'today' is associated with date and 'now' with time. However, it is a matter of expected behaviour of code rather than personal biases.
