I use:

def datefromiso(isoString, todayOnError=True):
    try:
        args = tuple(map(int, isoString.split(u'-')))
        return datetime.date(*args)
    except (TypeError, ValueError), x:
        if todayOnError:
            return datetime.date.today()
        else:
            raise x

def timefromiso(isoString, zeroOnError=True):
    try:
        args = tuple(map(int, isoString.split(u':')))
        return datetime.time(*args)
    except (TypeError, ValueError), x:
        if zeroOnError:
            return datetime.time(0)
        else:
            raise x

Lots of schools still structure Spring Break around Easter...since my
org works with youth to a large extent, that means we do about 1/8 of
our business for the year during Palm Sunday week and Easter week. Just
an example.
