Workalendar is a Python module that offers classes able to handle calendars, list legal / religious holidays and gives working-day-related computation functions.

This is barely beta. Please consider this module as a work in progres.

>>> from datetime import date
>>> from workalendar.europe import France
>>> cal = France()
>>> cal.holidays(2012)
[(datetime.date(2012, 1, 1), 'New year'),
 (datetime.date(2012, 4, 9), 'Easter Monday'),
 (datetime.date(2012, 5, 1), 'Labour Day'),
 (datetime.date(2012, 5, 8), 'Victory in Europe Day'),
 (datetime.date(2012, 5, 17), 'Ascension Day'),
 (datetime.date(2012, 5, 28), 'Whit Monday'),
 (datetime.date(2012, 7, 14), 'Bastille Day'),
 (datetime.date(2012, 8, 15), 'Assumption of Mary to Heaven'),
 (datetime.date(2012, 11, 1), "All Saints' Day"),
 (datetime.date(2012, 11, 11), 'Armistice Day'),
 (datetime.date(2012, 12, 25), 'Christmas')]
>>> cal.is_working_day(date(2012, 12, 25))  # it's Christmas
False
>>> cal.is_working_day(date(2012, 12, 30))  # it's Sunday
False
>>> cal.is_working_day(date(2012, 12, 26))
True

Please take note that some calendars are not 100% accurate. The most common example is the Islamic calendar, where some computed holidays are not exactly on the same official day decided by religious authorities, and this may vary country by country. Whenever it's possible, try to adjust your results with the official data provided by the adequate authorities.
