The `workday` binary sensor indicates, whether the current day is a workday or not. It allows specifying, which days of the week counts as workdays and also uses the python module [holidays](https://pypi.python.org/pypi/holidays) to incorporate information about region-specific public holidays.

To enable the `workday` sensor in your installation, add the following to your `configuration.yaml` file:

```yaml
# Example configuation.yaml entry
binary_sensor:
  - platform: workday
    country: DE
```

Configuration variables:

- **country** (*Required*): Country code according to [holidays](https://pypi.python.org/pypi/holidays/0.8.1) notation.
- **province** (*Optional*): Province code according to [holidays](https://pypi.python.org/pypi/holidays/0.8.1) notation. Defaults to None.
- **workdays** (*Optional*): List of workdays. Defaults to `mon`, `tue`, `wed`, `thu`, `fri`.
- **excludes** (*Optional*): List of workday excludes. Defaults to `sat`, `sun`, `holiday`.

Days are specified as follows: `mon`, `tue`, `wed`, `thu`, `fri`, `sat`, `sun`. The keyword `holiday` is used for public holidays identified by the holidays module.

<p class='note warning'>
If you use the sensor for Canada (`CA`) with Ontario (`ON`) as `province:` then you need to wrap `ON` in quotes. Otherwise the value is evaluated as `True` (check the YAML documentation for further details) and the sensor will not work.

Example usage for automation:

```yaml
automation:
  alias: Turn on heater on workdays
  trigger:
    platform: time
    after: '08:00:00'
  condition:
    condition: state
    entity_id: 'binary_sensor.workday_sensor'
    state: 'on'
  action:
    service: switch.turn_on
    entity_id: switch.heater
```
