workalendar/workalendar: Worldwide holidays and workdays computational toolkit.

原作者: [db:作者] 来自: 网络 收藏 邀请

开源软件名称(OpenSource Name):

开源软件介绍(OpenSource Introduction):

Workalendar

license pypi conda

Overview

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

Installation

With pip

pip install workalendar

With conda

conda install -c conda-forge workalendar

Extra dependencies

Note: NEW in v16.0.0

If the calendar(s) you want to work with requires astronomical computations (such as Asian calendars needing equinoxes or solar terms), Workalendar will provide pre-computed values within the year range from 1991 to 2051.

However, if you want to use astronomical libraries to compute the calendar yourself, you'll need to install the [astronomy] extra dependency like this:

pip install workalendar[astronomy]

If you had previously installed the skyfield and skyfield-data packages, they'll be used to compute the calendars. If you want to benefit from the "astronomical cache", and eventually benefit from performance gains, you'll have to uninstall those packages first to fallback to pre-computed files.

Status

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.

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

External dependencies

Workalendar will require you to use Python 3.6+.

Workalendar is tested on Python 3.6, 3.7, 3.8, 3.9, and on Linux (Ubuntu), Mac OS and Windows using Github actions.

Conditional dependencies

As of v15.0.0:

  • If you're using *Nix and Python 3.6, 3.7, 3.8, the package backports.zoneinfo is required
  • If you're using Windows and Python 3.6, 3.7, 3.8, the package tzdata is also a requirement (with the backports.zoneinfo).
  • If you're using Python 3.9+, the stdlib zoneinfo package will be used.

Tests

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.

Some countries have some holidays based on ephemerids and equinoxes. Those are computed for the previous and next 30 years to prevent big computations and dependencies.

History

This project was born in 2013, as an answer to the question "how do we calculate this date + 5 working days?". It was a use-case for PeopleDoc, in their ticketing application, for calculating SLAs. And it began as a small open-source library, for France and the USA at first.

Thanks to PeopleDoc, this project grew and eventually became a world-wide library, with the help of dozens of contributors.

As of June 2021, this project has moved to its own organization.
