A fast, efficient Python library for generating country- and subdivision- (e.g. state or province) specific sets of government-designated holidays on the fly. It aims to make determining whether a specific date is a holiday as fast and flexible as possible.

from datetime import date
import holidays

us_holidays = holidays.US()  # this is a dict
# the below is the same, but takes a string:
us_holidays = holidays.country_holidays('US')  # this is a dict

nyse_holidays = holidays.NYSE()  # this is a dict
# the below is the same, but takes a string:
nyse_holidays = holidays.financial_holidays('NYSE')  # this is a dict

date(2015, 1, 1) in us_holidays  # True
date(2015, 1, 2) in us_holidays  # False
us_holidays.get('2014-01-01')  # "New Year's Day"

The HolidayBase dict-like class will also recognize date strings and Unix timestamps:

'2014-01-01' in us_holidays  # True
'1/1/2014' in us_holidays    # True
1388597445 in us_holidays    # True

Some holidays may be only present in parts of a country:

us_pr_holidays = holidays.country_holidays('US', subdiv='PR')
'2018-01-06' in us_holidays     # False
'2018-01-06' in us_pr_holidays  # True

Please see the python-holidays documentation for additional examples and detailed information.

We currently support 135 country codes. The standard way to refer to a country is by using its ISO 3166-1 alpha-2 code, the same used for domain names, and for a subdivision its ISO 3166-2 code. Some of the countries support more than one language for holiday names output. A default language is defined by default_language (optional) attribute for each entity and is used as a fallback when neither user specified language nor user locale language available. The default language code is a ISO 639-1 code. A list of all languages supported by country is defined by supported_languages (optional) attribute. If there is no designated ISO 639-1 code then ISO 639-2 code can be used.

The list of supported countries, their subdivisions and supported languages (all default values are hightlighted with bold):

The standard way to refer to a financial market is to use its ISO 10383 MIC (Market Identifier Code) as a "country" code when available. The following financial markets are available:
