This is a very simple python code snippet for calculating the difference between two dates or timestamps. This will calculate the difference in terms of number of years, months, days, hours, minutes etc. For more details, refer https://amalgjose.com/2015/02/19/python-code-for-calculating-the-difference-between-two-time-stamps/

DateDifference.py

from datetime import datetime
from dateutil import relativedelta

##Aug 7 1989 8:10 pm
date_1 = datetime(1989, 8, 7, 20, 10)

##Dec 5 1990 5:20 am
date_2 = datetime(1990, 12, 5, 5, 20)

#This will find the difference between the two dates
difference = relativedelta.relativedelta(date_2, date_1)

years = difference.years
months = difference.months
days = difference.days
hours = difference.hours
minutes = difference.minutes

print "Difference is %s year, %s months, %s days, %s hours, %s minutes " %(years, months, days, hours, minutes)

Well done amalgjose!

Is this snippet okay to use?

Thanks!

@oinga Yes you can use it.

# 
from datetime import datetime
from dateutil import relativedelta

# today date 

today = datetime.today()

# year in the past 

yr_p = today.replace(year = 2015)

difference = relativedelta.relativedelta(today, yr_p)

years = difference.years
months = difference.months
weeks = difference.weeks
days = difference.days

print(f"The differnce in year: {years}, in months: {months}, in weeks: {weeks}, in days: {days}")

Great code, but any ideas why it does not print the months, weeks, days in my altered code?

How to Write a Python script to display the examination schedule. Extract the exam date from user and calculate the days left for the examination from current date.
output should be like this
Exam date: (2016/12/30)
Current date: (2016/12/15)
Expected output: 15 days
