#   @package        :   Holidays
#   @description    :   Holiday Specific.
#
#   I'm not sure where I got this, but it leverages a python script: https://github.com/thejeffreystone/home-assistant-configuration/blob/master/python_scripts/special_events.py
#
#   To create a sensor just create an automation to fire around midnight.
#
#   automation:
#   - id: refresh_holioday_sensors
#     alias: Refresh Holiday sensors
#     initial_state: true
#     trigger:
#     - platform: time
#       at: '00:00:07'
#     - platform: homeassistant
#       event: start
#     action:
#     - service: python_script.special_events
#       data:
#         name: Christmas
#         type: holiday
#         date: 25/12/2001
#
#   Where Name equals the name of the event, type is the type of event, and date is the date in DD/MM/YYYY format
# 
#   Year only matters if your want to take advantage fo the years attribute which will tell you have many years since the event. Useful 
#   with birthdays and anniversaries.
# 
#   I use the Following types:
#   birthday
#   anniversary
#   holiday
#   trip
#   
#   The type will be used in the name of the sensor it creates. For example:
#   sensor.trip_camping
#   sensor.birthday_jeff
#   sensor.holiday_christmas
#
#   The state of the sensor will be the days until the event. For birthdays and anniversaries it will never be more than 365. 
#   For example {{ states.sensor.birthday_jeff.state }} will be the number of days until my next birthday. 
#   And {{ states.sensor.birthday_jeff.attributes.years }} will be my age, or the number of years since my birth (if you put the real year in)
#   For events with a year in the future, the state will be number of days to that exact moment in time.
