The `season` sensor will display the current astronomical or meteorological season (Spring, Summer, Autumn, Winter) based on the user's setting in the configuration file.

For information on the difference between astronomical and meteorological seasons please see the link below:

- [https://www.ncei.noaa.gov/news/meteorological-versus-astronomical-seasons](https://www.ncei.noaa.gov/news/meteorological-versus-astronomical-seasons)

All information about how the seasons work was taken from Wikipedia:

- [https://en.wikipedia.org/wiki/Season#Astronomical](https://en.wikipedia.org/wiki/Season#Astronomical)
- [https://en.wikipedia.org/wiki/Equinox](https://en.wikipedia.org/wiki/Equinox)
- [https://en.wikipedia.org/wiki/Solstice](https://en.wikipedia.org/wiki/Solstice)

To cut a long read short, `astronomical` gives seasons based on the shortest/longest day and equinoxes. So in the Northern Hemisphere spring starts on 20 March). `meteorological` gives seasons based on months (so in the Northern Hemisphere spring starts on 1 March).

## Configuration

To enable the sensor, add the following lines to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  - platform: season
```
