I work for a company that processes claims for the health care industry (Novasys Health, recently purchased by Centene Corp). My current assignment has me writing a routine to compute insurance premiums. One of the requirements is to determine how many months a policy has been in effect. The datetime module will give me the number of days but, with months having different lengths, that does not do me much good. I've looked in the calendar library but didn't see anything there, either.
I've written a function to return the months between date1 and date2 but I'd like to know if anyone is aware of anything in the standard library to do the same? For bonus points, does anyone know if postgres can do the same (we use a lot of date/time funcitons in postgres, already, but didn't see this problem addressed). On a side note; since I'm dealing with money (USD), I decided to use the decimal module for all computations. It's not a big difference -- unless you've seen the movie "Office Space" :-) -- but it sure is nice. Especially being able to easily round values to the nearest cent. You just have to love the standard library. Thanks for your help, --greg
