How to calculate the difference in years between two dates in…

datetime1 = datetime. datetime(2000, 1, 1)
datetime2 = datetime. datetime(2010, 1, 1)
time_difference = relativedelta(datetime2, datetime1)
difference_in_years = time_difference. years.
print(difference_in_years, “years”)

What is the difference between Timedelta and Relativedelta?

While timedelta only offers plural nouns (e.g. hours , days ) to denote relative time difference, relativedelta offers singular nouns as well (e.g. hour , day ) to denote absolute time information.

Can you subtract dates in Pandas?

Python includes some great features for reformatting dates, so it’s actually quite easy to add and subtract from dates, thanks to the timedelta() function, and it works seamlessly in Pandas. Here’s how to do it.

How do you count 12 months?
