And the best part is the Ruby way accounts for leap years.

Well,
365 * 10certainly doesn't ;-) -
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
py
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())

there is a simple fix to account for leap years, just add 10/4 days. /s
-
Don't forget non-leap-days every 200 years!
-
Every 100 years but not every 400 years! Isn't it fun?
