# Goodtimer

This is a simple countdown in plain html+css+javascript. You can either host it yourself (just serve the files in this repository with a web server) or use https://goodtimer.lubiland.de

The target date is specified behind a hash (#) and in any [ECMAScript Date Time String Format](https://tc39.es/ecma262/#sec-date-time-string-format). When you omit the timezone it uses the local time of the browser.

Here are some example URLs:

https://goodtimer.lubiland.de/#2020-11-24T00:00+01:00  
https://goodtimer.lubiland.de/#2020-11-24T00:00  
https://goodtimer.lubiland.de/#2020-11-24  
https://goodtimer.lubiland.de/#2020-11  
https://goodtimer.lubiland.de/#2021  

## Matrix widget

Goodtimer is also usable as widget for [Matrix](https://matrix.org) clients. Either specify the URL as 'Custom Widget' within [Element](https://element.io) or manually send something like this example event:

type: im.vector.modular.widgets  
state_key: shadowlands-release

```json
{
	"type": "customwidget",
	"url": "https://goodtimer.lubiland.de/#2020-11-24T00:00+01:00",
	"name": "Shadowlands Release",
	"data": {
		"curl": "https://goodtimer.lubiland.de/"
	}
}
```
