Detecting a US Holiday

Question

What's the simplest way to determine if a date is a U.S. bank holiday in Python? There seem to be various calendars and webservices listing holidays for various countries, but I haven't found anything specific to banks in the U.S.

Answer 1

The Pandas package provides a convenient solution for this:

from pandas.tseries.holiday import USFederalHolidayCalendar cal = USFederalHolidayCalendar() holidays = cal.holidays(start='2014-01-01', end='2014-12-31').to_pydatetime() if datetime.datetime(2014,01,01) in holidays:     print True  

Answer 2

Use the holiday library in python.

pip install holidays

For USA holiday:

1. To check a date holiday or not.

from datetime import date import holidays  # Select country us_holidays = holidays.US()  # If it is a holidays then it returns True else False print('01-01-2018' in us_holidays) print('02-01-2018' in us_holidays)  # What holidays is it? print(us_holidays.get('01-01-2018')) print(us_holidays.get('02-01-2018')) 

2. To list out all holidays in US:

from datetime import date import holidays  # Select country us_holidays = holidays.US()  # Print all the holidays in US in year 2018 for ptr in holidays.US(years = 2018).items():     print(ptr)
