calendra 1.1

Worldwide holidays and working days helper and toolkit.

Overview

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

History

Calendra is a fork of Workalendar designed to be more extensible and introspectable, adding interfaces where Workalendar is philosophically opposed for the sake of simplicity.

Status

The project is stable and in production use. Calendra follows the principles of semver for released verisons.

Usage sample

>>> 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

Caveats

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.
