'''Question: 
Write a Python program to calculate two date difference in seconds.
'''

# Python code: 

from datetime import datetime, time

def date_diff_in_Seconds(dt2, dt1):

  timedelta = dt2 - dt1

  return timedelta.days * 24 * 3600 + timedelta.seconds

#Specified date

date1 = datetime.strptime('2015-01-01 01:00:00', '%Y-%m-%d %H:%M:%S')

#Current date

date2 = datetime.now()

print("\n%d seconds" %(date_diff_in_Seconds(date2, date1)))

print()



'''Output sample: 
74175795 seconds
