Question

Given datetime.datetime.now(), how do I get this week’s Monday – Sunday and then the same Monday – Sunday for last year, considering leap years?

One idea I had was to get the timedelta for -365 days and then find the nearest Monday or Sunday. I’m sure there is a better way.

Edit: I don’t mind using datetuil, if there is something in there that’d make this easier.

Answer 1

If using dateutil is not a problem, just use it 🙂

The relativedelta is the object you need
Here you will be able to substract one year to the current date.

from datetime import *
from dateutil.relativedelta import *
NOW = datetime.now()
last_monday = NOW+relativedelta(years=-1, weekday=MO)
last_sunday = NOW+relativedelta(years=-1, weekday=SU)
