This sounds like a perfect place for a custom generator function.
def timecount(start, **delta):
delta = datetime.timedelta(**delta)
while True:
yield start
start += delta
timecount(datetime.date.today(), days=1)
The default itertools.count is highly optimized for its job, but when
you need flexibility, it's easy enough to handroll something to your
needs.
