Custom countdown clock

I have some custom code for a countdown clock. The code works great except that the clock gets stuck at 1 second. I’m using the code for a church that has a live service every week at the same time.

The countdown ends on sunday at 10am, I would love for it to be able to auto reset on Monday so I don’t have to manually reset it each week. It would also be awesome when the clock hits zero, that the clock hides and then unhides a button that says join us live now. Could someone help me figure this out? I’ve listed the code below. Thanks!

Hey Simply U, if you’re looking for help, your code and readonly link are missing.
In this case seeing the current code in operation is important too, so a link to a published site would help.
