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

This library is ready for production, although we may warn eventual users: some calendars may not be up-to-date, and this library doesn't cover all the existing countries on earth (yet).

If you spot any bug or wish to add a calendar, please refer to the Contributing doc.

>>> 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
>>> cal.add_working_days(date(2012, 12, 23), 5)  # 5 working days after Xmas
datetime.date(2012, 12, 31)

And more to come (I hope!)

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.
