Day's until Xmas

Last night there was a question on Jay's Virtual Pub Quiz asking how many days there were until Xmas. I worked something up years ago but decided to revisit it today while waiting for Visual Studio to build my solution, this is the result:

const days2Xmas = Math.ceil(
  (
    new Date(
      new Date().getMonth() == 11 && new Date().getDate() > 25 ?
      new Date().getFullYear() + 1 :
      new Date().getFullYear(),
      11,
      25
    )
    .getTime() -
    new Date().getTime()
  ) /
  (1000 * 60 * 60 * 24)
)
console.log(days2Xmas)
