Simple client-side only countdown. Live at https://countdown.markng.com/
You can create countdown links without using the website GUI like this:
- Create a JSON object like this and turn it into a string: (minify it, ideally)
{
"eventName": "Event name",
"unix": <unix time of the event>,
"createdAt": <unix time of the creation date of the event>
}
- Base64 encode that JSON string
- Pass it to the countdown website URL with the parameter
countdown=<the base64 encoded JSON string>
.
