How to correctly calculate time between datetime dates?

Question

Python

I have the following date, for example: 2006-10-01 (yyyy-mm-dd).
I need to calculate the number of years, months and days between a given date and the current one.
I tried many options, but for some reason datetime does not take into account leap years.
Here is an example of my code:

date = "2006-09-23"
date_object = datetime.datetime.strptime(date, "%Y-%m-%d")
delta = datetime.datetime.now() + datetime.timedelta(seconds=-date_object.timestamp()
return 'Аккаунт зарегистрирован: ' + date + '\n' + str(int(delta.strftime('%Y')) - 1970) + ' лет, ' + str(int(delta.strftime('%m')) - 1) + ' месяцев, ' + str(int(delta.strftime('%d')) - 1) + ' дней.'

If there was one leap year between the dates, I get one extra day in the calculation, two leap years - two extra days.
That is, in fact, at the current moment 10 years, 3 months, 29 days have passed between the dates, however, my program returns that 10 years, 4 months, 1 day have passed between the dates. It works correctly only if there were no leap years between the dates.
How to solve this problem?

Answer 1

Here they claim the existence of the calendar module , which takes into account leap years
