Next Holiday Sensor

This sensor tells you what holiday is coming up next. You can use it to set holiday light colors or other scenes.

The state of the sensor tells you what the upcoming holiday is. If today is a holiday, the state will be that holiday. There are sensor attributes showing all the holidays for the year, whether or not today is a holiday, and how many days there are before the next holiday. The component will look ahead into the next year for the next holiday.

Holidays are recomputed every year. In the config you can specify what holidays you want to track. The holidays and config are based on the https://github.com/dr-prodigy/python-holidays

Configuration

Configuration is set as a sensor of the next_holiday platform. You make a list of sources, each of which can have the following attributes:

Attribute	Type	Description	Example
country	str	A country to load holidays from	'USA'
state	str	A state within the country for state holidays	'WA'
province	str	A province within the country for state holidays	'ON'
multiday	bool	If true (default), holidays that span multiple days will be shown mulitiple times. Otherwise, only the first day will be shown	true
observed	bool	If true (default), observed holidays will be included in addition to real ones	true
filter	list of str	A filter where only holidays matching the query will be added	[See below]
exclude	list of str	An exclusion filter where holiday names that match an entry will be ignored	[Same as for filter]
kwargs	dict	A dict of key/value pairs that will be passed on to the underlying library. This can be used to activate special behavior for certain countries (like turning off Sundays for Norway)	[See below]

Multiple country/state/provinces and filters may be combined to get a pretty flexible list of holidays.

See this list of countries and languages that are supported. You can set language using the kwargs configuration with a language key, as demonstrated in the examples below for Norwegian.

Lists of valid states and province abbreviations can be found in the underlying library, e.g. here for Canada

There are also global configuration settings that you can specify, including:

Attribute	Type	Description	Example
min_future_holidays	int	The minimum number of future holidays before the system looks ahead into the next year	3
custom_holidays	dict	Additional month/day:holiday combos to add	{}

Example

Add a sensor to your configuration along the lines of:

sensor:
  - platform: next_holiday
    min_future_holidays: 3
    custom_holidays:
        "10-31": "Halloween"
    sources: 
     - country: "USA"
       state: "WA"
       exclude:
         - "washington's birthday"
     - country: "Israel"
       multiday: false
       filter:
         - "hanukkah"
     - country: "Norway"
       kwargs:
         include_sundays: false
         language: 'no'

This loads all normal holidays for the US State of Washington and also throws in Hanukkah by loading the Israel holidays and filtering everything but Hanukkah out. It also adds Halloween on Oct 31 of the year (which isn't really a national holiday anywhere).

Norwegian holidays are added as well. But because Norway considers every Sunday a holiday, we pass the special include_holidays flag down to the underlying library to avoid tracking them.
