>>> from datetime import datetime as dt
>>> a = dt.strptime("10/12/13", "%m/%d/%y")

>>> from datetime import datetime, timedelta
>>> past = datetime.now() - timedelta(days=1)
>>> present = datetime.now()
>>> past < present
True
>>> datetime(3000, 1, 1) < present
False

datetime.timedelta(4242, 75703, 762105)

# If you convert all your date to `datetime.date`, you can write the following:
if start <= date <= end:
    print("in between")
else:
    print("No!")
