This is a Rust implementation of cinnamon’s [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 don’t provide a configuration file, the day parts (day/night time and the golden/blue hours) won’t be visible on the clock face.
|
||||
|
||||
## Features
|
||||
|
||||
### Seasonal hours!
