A short script to create a ‘days left’ widget. It’s really just a rip-off of the sample news widget included with Scriptable. The Cabin Sketch font is from Google Fonts and installed with Fontcase.

DaysLeft.js

// Variables
let daysNumber = await loadTimeLeft()
let widget = await createWidget(daysNumber)
// Check if the script is running in
// a widget. If not, show a preview of
// the widget to easier debug it.
if (!config.runsInWidget) {
  await widget.presentSmall()
}
// Tell the system to show the widget.
Script.setWidget(widget)
Script.complete()

async function createWidget(items) {
  let w = new ListWidget()
  w.backgroundColor = new Color("#b00a0f")
  let titleTxt = w.addText(daysNumber.toLocaleString())
  titleTxt.font = new Font('Cabin Sketch', 96)
  titleTxt.centerAlignText()
  switch (daysNumber) {
    case 1:
      var daysText = 'day left.';
      break;
    default:
      var daysText = 'days left.';
    }
    let subtext = w.addText(daysText)
    subtext.font = new Font('Cabin Sketch', 24)
    subtext.centerAlignText()
    titleTxt.textColor = Color.white()
  return w
}

async function loadTimeLeft() {
  var end = new Date('12/21/2020 5:00 PM');
  var now = new Date();
  var left = Math.ceil((end - now)/(1000*60*60*24));
  return left;
}
