Custom Drupal 8 Jquery countdown timer

I have a website that runs Drupal 8. It has the module "Jquery Countdown Timer" - [login to view URL] installed. I need a "drop down select list" that will hold multiple values along with value names, it will also need to update the countdown timer using the new date when it's selected from the list. I would like the countdown timer to automatically update without refreshing the whole page. Each countdown 'date' will also require a 'link' next to the timer which when selected will redirect to a custom url(that should be preset on the module's configuration page) I also require the module to be able to accept years above the year 2032(it's the Y2k32 bug). You will not be given server access as it's not needed, to complete the project all I require is the "drupal 8 jquery countdown timer module" files that can be used on my system, you can get a copy of these files from the link above. What I require the module to do can be seen in the attached images.
