The literal answer to your question is, unsurprisingly, "Yes".

Now, what do you really want/need:

(a) details of an algorithm so that you can code it in Python
(b) an implementation of (a)
(c) a hint that Python might already have a standard module for date 
calculations
(d) a hint that there are things called search engines ... just copy 
your subject and paste it in

There is no such thing as "the" (unqualified) epoch.

Try days_difference(from_date=your_chosen_epoch, to_date=some_date) * 24 
* 60 * 60
