How much time is left until x. — This blog post lives now on my personal blog. View on Github Why? While I was building a landing page for an event recently, I noticed that I would love to have a dynamic timer stating how many days, hours and minutes are left until this awesome event will take place. Since I chose to build the page quickly with React, I searched for React countdown components. I didn’t find any component that could get the task done, so I wrote my own little component, called react-countdown.
