I prefer the one on the left because it's evident it doesn't account for leap days, while I'd be questioning whether the one on the right does.

I'll give it a shot. Looks a bit kludgy and I've been typing this on my phone while sitting on the toilet. What am I doing with my life?

from datetime import datetime 

now = datetime.now()
year = now.strftime('%Y')
month = now.strftime('%m')
day = now.strftime('%d')
tenyearsago = datetime(year-10, month, day)
print(tenyearsago.strftime('%d.%m.%Y')

And what happens when you run that on Feb 29, 2024?

datetime raises a ValueError when trying to create an invalid date

or just this

from datetime import datetime

today = datetime.today()
ten_years_ago = today.replace(year=today.year - 10)
print("Date 10 years ago:", ten_years_ago.date())
