If it bugs you, add a cache to _localized_name:

class _localized_name:
    def __init__(self, format):
        self.format = format
        self.cache = {}
    def __getitem__(self, item):
        return self.cache.setdefault(item,
                        strftime(self.format, (item,)*9).capitalize())

Are you saying that printing calendars is in the same
"performance critical" league as the IBM OS kernel?

Hope you feel better <wink>.
