=============== python-holidays

A fast, efficient Python library for generating country, province and state specific sets of holidays on the fly. It aims to make determining whether a specific date is a holiday as fast and flexible as possible.

Example Usage

.. code-block:: python

from datetime import date

import holidays

us_holidays = holidays.UnitedStates()
# or:
# us_holidays = holidays.US()
# or:
# us_holidays = holidays.CountryHoliday('US')
# or, for specific prov / states:
# us_holidays = holidays.CountryHoliday('US', prov=None, state='CA')

date(2015, 1, 1) in us_holidays  # True
date(2015, 1, 2) in us_holidays  # False

# The Holiday class will also recognize strings of any format
# and int/float representing a Unix timestamp
'2014-01-01' in us_holidays  # True
'1/1/2014' in us_holidays    # True
1388597445 in us_holidays    # True

us_holidays.get('2014-01-01')  # "New Year's Day"

us_holidays['2014-01-01': '2014-01-03']  # [date(2014, 1, 1)]

us_pr_holidays = holidays.UnitedStates(state='PR')  # or holidays.US(...), or holidays.CountryHoliday('US', state='PR')

# some holidays are only present in parts of a country
'2018-01-06' in us_holidays     # False
'2018-01-06' in us_pr_holidays  # True

# Easily create custom Holiday objects with your own dates instead
# of using the pre-defined countries/states/provinces available
custom_holidays = holidays.HolidayBase()
# Append custom holiday dates by passing:
# 1) a dict with date/name key/value pairs,
custom_holidays.append({"2015-01-01": "New Year's Day"})
# 2) a list of dates (in any format: date, datetime, string, integer),
custom_holidays.append(['2015-07-01', '07/04/2015'])
# 3) a single date item
custom_holidays.append(date(2015, 12, 25))

date(2015, 1, 1) in custom_holidays  # True
date(2015, 1, 2) in custom_holidays  # False
'12/25/2015' in custom_holidays      # True

# For more complex logic like 4th Monday of January, you can inherit the
# HolidayBase class and define your own _populate(year) method. See below
# documentation for examples.

API

class holidays.HolidayBase(years=[], expand=True, observed=True, prov=None, state=None) The base class used to create holiday country classes.

Parameters:

years An iterable list of integers specifying the years that the Holiday object should pre-generate. This would generally only be used if setting expand to False. (Default: [])

expand A boolean value which specifies whether or not to append holidays in new years to the holidays object. (Default: True)

observed A boolean value which when set to True will include the observed day of a holiday that falls on a weekend, when appropriate. (Default: True)

prov A string specifying a province that has unique statutory holidays. (Default: Australia='ACT', Canada='ON', NewZealand=None)

state A string specifying a state that has unique statutory holidays. (Default: UnitedStates=None)

Methods:

get(key, default=None) Returns a string containing the name of the holiday(s) in date key, which can be of date, datetime, string, unicode, bytes, integer or float type. If multiple holidays fall on the same date the names will be separated by commas

get(key, default=None) Returns a string containing the name of the holiday(s) in date key, which can be of date, datetime, string, unicode, bytes, integer or float type. If multiple holidays fall on the same date the names will be separated by commas

get_list(key) Same as get except returns a list of holiday names instead of a comma separated string

get_named(name) Returns a list of holidays matching (even partially) the provided name (case insensitive check)

pop(key, default=None) Same as get except the key is removed from the holiday object

pop_named(name) Same as pop but takes the name of the holiday (or part of it) rather than the date

update/append Accepts dictionary of {date: name} pairs, a list of dates, or even singular date/string/timestamp objects and adds them to the list of holidays

More Examples

.. code-block:: python

# Simplest example possible

>>> from datetime import date
>>> import holidays
>>> date(2014, 1, 1) in holidays.US()
True
>> date(2014, 1, 2) in holidays.US()
False

# But this is not efficient because it is initializing a new Holiday object
# and generating a list of all the holidays in 2014 during each comparison

# It is more efficient to create the object only once

>>> us_holidays = holidays.US()
>>> date(2014, 1, 1) in us_holidays
True
>> date(2014, 1, 2) in us_holidays
False

# Each country has three class names that can be called--a full name
# and the 2 and 3-digit ISO codes. Use whichever you prefer.

>>> holidays.UnitedStates() == holidays.US()
True
>>> holidays.Canada() == holidays.CA()
True
>>> holidays.US() == holidays.CA()
False

# Let's print out the holidays in 2014 specific to California, USA

>>> for date, name in sorted(holidays.US(state='CA', years=2014).items()):
>>>     print(date, name)
2014-01-01 New Year's Day
2014-01-20 Martin Luther King Jr. Day
2014-02-15 Susan B. Anthony Day
2014-02-17 Washington's Birthday
2014-03-31 César Chávez Day
2014-05-26 Memorial Day
2014-07-04 Independence Day
2014-09-01 Labor Day
2014-10-13 Columbus Day
2014-11-11 Veterans Day
2014-11-27 Thanksgiving
2014-12-25 Christmas Day

# So far we've only checked holidays in 2014 so that's the only year the
# Holidays object has generated

>>> us_holidays.years
set([2014])
>>> len(us_holidays)
10

# Because by default the `expand` param is True the Holiday object will add
# holidays from other years as they are required.

>>> date(2013, 1, 1) in us_holidays
True
>>> us_holidays.years
set([2013, 2014])
>>> len(us_holidays)
20

# If we change the `expand` param to False the Holiday object will no longer
# add holidays from new years

>>> us_holidays.expand = False
>>> date(2012, 1, 1) in us_holidays
False
>>> us.holidays.expand = True
>>> date(2012, 1, 1) in us_holidays
True

# January 1st, 2012 fell on a Sunday so the statutory holiday was observed
# on the 2nd. By default the `observed` param is True so the holiday list
# will include January 2nd, 2012 as a holiday.

>>> date(2012, 1, 1) in us_holidays
True
>>> us_holidays[date(2012, 1, 1)]
"New Year's Day"
>>> date(2012, 1, 2) in us_holidays
True
>>> us_holidays.get(date(2012 ,1, 2))
"New Year's Day (Observed)"

# The `observed` and `expand` values can both be changed on the fly and the
# holiday list will be adjusted accordingly

>>> us_holidays.observed = False
>>> date(2012, 1, 2) in us_holidays
False
us_holidays.observed = True
>> date(2012, 1, 2) in us_holidays
True

# Holiday objects can be added together and the resulting object will
# generate the holidays from all of the initial objects

>>> north_america = holidays.CA() + holidays.US() + holidays.MX()
>>> north_america.get('2014-07-01')
"Canada Day"
>>> north_america.get('2014-07-04')
"Independence Day"

# The other form of addition is also available

>>> north_america = holidays.Canada()
>>> north_america += holidays.UnitedStates()
>>> north_america += holidays.Mexico()
>>> north_america.country
['CA', 'US', 'MX']

# We can even get a set of holidays that include all the province- or
# state-specific holidays using the built-in sum() function
>>> a = sum([holidays.CA(prov=x) for x in holidays.CA.PROVINCES])
>>> a.prov
PROVINCES = ['AB', 'BC', 'MB', 'NB', 'NL', 'NS', 'NT', 'NU', 'ON', 'PE',
             'QC', 'SK', 'YU']

# Holidays can be retrieved using their name too.
# `get_named(key)` receives a string and returns a list of holidays
# matching it (even partially, with case insensitive check)

>>> us_holidays = holidays.UnitedStates(years=2020)
>>> us_holidays.get_named('day')
[datetime.date(2020, 1, 1), datetime.date(2020, 1, 20),
datetime.date(2020, 2, 17), datetime.date(2020, 5, 25),
datetime.date(2020, 7, 4), datetime.date(2020, 7, 3),
datetime.date(2020, 9, 7), datetime.date(2020, 10, 12),
datetime.date(2020, 11, 11), datetime.date(2020, 12, 25)]

# Sometimes we may not be able to use the official federal statutory
# holiday list in our code. Let's pretend we work for a company that
# does not include Columbus Day as a statutory holiday but does include
# "Ninja Turtle Day" on July 13th. We can create a new class that inherits
# the UnitedStates class and the only method we need to override is _populate()

>>> class CorporateHolidays(holidays.UnitedStates):
>>>     def _populate(self, year):
>>>         # Populate the holiday list with the default US holidays
>>>         holidays.UnitedStates._populate(self, year)
>>>         # Remove Columbus Day
>>>         self.pop_named("Columbus Day")
>>>         # Add Ninja Turtle Day
>>>         self[date(year, 7, 13)] = "Ninja Turtle Day"
>>> date(2014, 10, 14) in Holidays(country="US")
True
>>> date(2014, 10, 14) in CorporateHolidays(country="US")
False
>>> date(2014, 7, 13) in Holidays(country="US")
False
>>> date(2014 ,7, 13) in CorporateHolidays(country="US")
True

# We can also inherit from the HolidayBase class which has an empty
# _populate method so we start with no holidays and must define them
# all ourselves. This is how we would create a holidays class for a country
# that is not supported yet.

>>> class NewCountryHolidays(holidays.HolidayBase):
>>>     def _populate(self, year):
>>>         self[date(year, 1, 2)] = "Some Federal Holiday"
>>>         self[date(year, 2, 3)] = "Another Federal Holiday"
>>> hdays = NewCountryHolidays()

# We can also include prov/state specific holidays in our new class.

>>> class NewCountryHolidays(holidays.HolidayBase):
>>>     def _populate(self, year):
>>>         # Set default prov if not provided
>>>         if self.prov == None:
>>>             self.prov = 'XX'
>>>         self[date(year, 1, 2)] = "Some Federal Holiday"
>>>         if self.prov == 'XX':
>>>             self[date(year, 2, 3)] = "Special XX province-only holiday"
>>>         if self.prov == 'YY':
>>>             self[date(year, 3, 4)] = "Special YY province-only holiday"
>>> hdays = NewCountryHolidays()
>>> hdays = NewCountryHolidays(prov='XX')

# If you write the code necessary to create a holiday class for a country
# not currently supported please contribute your code to the project!

# Perhaps you just have a list of dates that are holidays and want to turn
# them into a Holiday class to access all the useful functionality. You can
# use the append() method which accepts a dictionary of {date: name} pairs,
# a list of dates, or even singular date/string/timestamp objects.

>>> custom_holidays = holidays.HolidayBase()
>>> custom_holidays.append(['2015-01-01', '07/04/2015'])
>>> custom_holidays.append(date(2015, 12, 25))
