Below code will explain how to find a difference in the minute,
if you have two dates, then you can find the difference of the time using divmode function of python

 >>> import datetime  
 >>> end = datetime.datetime.now()  
 >>> start = datetime.datetime.now()  
 >>> diff  
 datetime.timedelta(0, 7, 424199)  
 >>> diff = start - end  
 >>> divmod(diff.days * 86400 + diff.seconds, 60)  
 (0, 7) # 0 minutes, 7 seconds
