This is a Rust implementation of cinnamons [Seasonal Hours Clock](https://github.com/cinnamon-bun/seasonal-hours-clock), running as a native Wayland application.
## Configuration
Create a file `$XDG_CONFIG_HOME/seasonal-clock.toml` (where `$XDG_CONFIG_HOME` is `~/.config` on Linux systems) with the following content:
```
[seasonal-clock]
latitude = 47.655
longitude = 19.286
```
(this is a location around Hungary; you may want to change these.)
If you dont provide a configuration file, the day parts (day/night time and the golden/blue hours) wont be visible on the clock face.
## Features
### Seasonal hours!
