Today =
today = datetime.datetime.now().strftime("%Y%m%d")
90days ago
DD = datetime.timedelta(days=-90)
How do I get today - DD, or 90days ago?

You should be able to subtract time deltas from datetime objects.
today = datetime.datetime.now()
DD = datetime.timedelta(days=90)
earlier = today - DD
earlier_str = earlier.strftime("%Y%m%d")
Just subtract a timedelta from a datetime:
>>> import datetime
>>> today = datetime.datetime.today()
>>> DD = datetime.timedelta(days=90)
>>> today - DD
datetime.datetime(2010, 11, 3, 9, 56, 20, 924224)
(or if you want to use a negative timedelta like you did there, add them:
>>> DD = datetime.timedelta(days=-90)
>>> today + DD
datetime.datetime(2010, 11, 3, 9, 56, 20, 924224)
You need to subtract timedelta(days=90):
from datetime import date, datetime, timedelta
today = datetime.now()
dd = today - timedelta(days=90)
print(dd)
It should print 2010-11-03 15:04:42.289684.
from datetime import date,timedelta
currentDay = date.today()
requestedDay = currentDay - timedelta(days=90)
print(requestedDay)
hope it solves.
